Bordeaux is a city located in the southwest of France, about 45 kilometers from the Atlantic Ocean on the Garonne River, which runs in a wide arc through the city. This shape of a crescent moon helped the city get its name Port de la lune (Port of the Moon). A few kilometres downstream, the Garonne joins the Dordogne to form the Gironde estuary, which is over 70 kilometres long. Tidal forces can therefore be observed right into the city area. At high tide, the inflowing seawater pushes the river back and raises the level by about four to five metres. The resulting currents create eddies and turbulent surface water. At times, a veritable wave can move upstream for dozens of kilometres. This phenomenon is called mascaret (spring tide) in Bordeaux.
Geology
The left bank of the Garonne, on which by far the largest part of the urban area is located, consists of wide, marshy plains from which low hills rise. These are made up of boulder sediments and for the most part have gravel and crushed stone as subsoil. The soils are poor, but excellent for viticulture due to their water permeability and ability to retain heat. The city of Bordeaux lies between the downstream Médoc and the upstream Graves area, which are geomorphologically very similar. Famous wineries are not uncommon right into the heavily urbanized metropolitan area.
The right bank merges almost immediately into a limestone plateau up to 90 meters high, so that there is a striking escarpment there. The plateau is home to world-famous wine-growing regions such as Saint-Émilion, Pomerol and Fronsac, where some of the most expensive wines in the world are cultivated.
Climate
Bordeaux lies on the southern edge of the temperate climate zone. The very mild winters and the long, warm summers already allow subtropical-Mediterranean influence to be felt. Precipitation is frequent in all seasons; with a rainfall of over 900 millimeters per year, relatively high amounts are achieved by French standards. This falls mainly in the winter half of the year, in summer more in the form of heat thunderstorms. The highest amount of precipitation ever measured in France within half an hour was reported from Bordeaux in July 1883. Enormous damage was also caused by a "double thunderstorm" in 1982, when on 31 May the entire monthly rainfall was recorded within one hour, and three days later another half an hour within 50 minutes.
The annual mean temperature is about 12.8 °C with an average minimum of 5.9 °C in January and a maximum of 20.2 °C in July. The temporally shifted temperature maxima are due to the oceanic climate. Despite the balanced temperature cycle, extreme temperatures can occur in appropriate weather conditions: During the heat wave of 2003, the maximum values reached at least 35 °C on twelve consecutive days, including 41 °C on one day.
The city has a high level of sunshine. With about 2,000 hours of sunshine per year, Bordeaux surpasses most French regions, with the exception of the Mediterranean and some coastal areas on the Atlantic.
The microclimates of Bordeaux and its surroundings are one of the decisive factors for the excellent winegrowing conditions: The city and surrounding growing areas are protected from the sea winds by a wide strip of pine forest (Forêt des Landes). In addition, the Gironde provides a temperature-balancing effect, as this body of water releases heat stored during the day at night and also reflects solar radiation over a wide area into the surrounding countryside.

Neighborhood
Bordeaux is administratively divided into eight urban arrondissements. The arrondissements 1 to 6 are located on the left bank of the Garonne and are numbered from north to south, the seventh is the right bank of the Garonne and the eighth is the incorporated district of Caudéran. Since the historically grown was mostly not taken into account, this has led to the fact that the inhabitants do not identify themselves with their arrondissements - as for example in Paris. Instead, it is customary to indicate residence by neighborhoods or districts. Usually, these also give some indication of the standard of living.
Vieux Bordeaux (Old Town)
Since 2007, the old town of Bordeaux has been a UNESCO World Heritage Site under the designation Historic Centre of Bordeaux ("Port of the Moon"). The area inside the former city walls is the historic core of Bordeaux. It is bounded by the ring-shaped structure of the main streets and the banks of the Garonne, and divided by two main axes:
From north to south, the Rue Sainte-Catherine, over a kilometre long and today completely converted into a pedestrian zone, runs from the Place du Grand Théâtre to the Place de la Victoire, where the old university buildings stand. Here and to the west is the business district of Bordeaux with a focus on commerce and services, to the east as far as the Garonne, residential development predominates - some of it very old.
The east-west axis is formed by the Pont de pierre, the only bridge crossing within the historic centre. Its continuation is the Cours Victor Hugo. To the north, residential and commercial areas of high to very high standards predominate, to the south simple locations.
In the north-western part, in the Quinconces and Hôtel de Ville districts, you will find fine restaurants and cafés, prestigious branches of banks and financial service providers, cinemas and retail outlets for upmarket or luxury needs. Here lies the Triangle d'or (Golden Triangle), as it was known in the days of the Intendants, an almost equilateral triangle formed by three avenues and considered the showcase of fine Bordeaux. In the north-eastern part in the Saint-Pierre and Saint-Eloi neighbourhoods are restaurants, hotels and pubs. The original alternative charm is slowly giving way to a certain chic. The south-western part in the Victoire neighbourhood is strongly student-oriented, but also a preferred place to live for the middle class. In the southeast, in the Capucins, Saint-Michel and Sainte-Croix neighbourhoods, low-income groups predominate, including the elderly, workers, the unemployed and immigrants.
The former faubourgs (suburbs)
The residential belt between the Cours and the Boulevard developed from former suburbs outside the city walls and is, with exceptions, similarly structured: In the north preferred, in the south simple locations predominate.
Along the Garonne to the north are the Chartrons and Grand Parc districts, the former the home of many wine merchants and bourgeois in character, the latter a large housing estate for low-income classes.
The northwest around the Palais Gallien is home to the Saint-Seurin district, an upscale residential area and home to many consulates.
To the west rises the Mériadeck shopping and administrative centre, the only high-rise ensemble in the city centre. For its construction, large areas of simple quarters were demolished, the condition of which was considered dilapidated and unhygienic. Although high-quality residential development was planned between the commercial and administrative areas, there has been no increased settlement of the upper classes; on the contrary, the buildings have already taken on a slight patina. On the contrary, the buildings have already begun to show a slight patina. However, the generous transport infrastructure has led to the establishment of a number of hotels of a higher standard. Around Mériadeck, the original development for the lower to middle class has been preserved, consisting mostly of one- to two-storey rows of houses with small gardens. These so-called échoppes are very popular with the population today.
Saint Genès in the southwest has an upper middle-class character, while the station district in the south is still a residential area for the poor. Industry and commerce, railway lines and unappealing infrastructure such as the central slaughterhouses characterize the picture.
After decades of neglect, the right bank of the Garonne has come to the attention of urban planners. In place of the industrial and railway districts of Bastide and Benauge, a completely new residential district for the upper classes is being built directly opposite the old town. This is being done mainly in La Bastide on the southern area of the former railway and goods station site and the adjoining industrial estates. This began with the conversion of the old Gare d'Orléans station into a multiplex cinema and the opening of the Jardin botanique de Bordeaux botanical garden in 2003.
On the other side of the boulevard, to the north, lies the Lac district, with no residential development to speak of, and Bacalan, traditionally a dockworkers' district and now heavily marked by unemployment. To the west is Caudéran, a suburb that was incorporated in 1964, with loose buildings and a few prestigious villas. Here is located the Parc Bordelais, the largest public green space in the city. To the southwest is Saint-Augustin, a middle- to upper-middle-class neighborhood; here are the Stade Chaban-Delmas stadium and the Central Hospital.
Agglomeration
As in almost all French conurbations, the core city of Bordeaux is surrounded by a belt of independent municipalities that have grown inseparably together with it but have not been incorporated. While Bordeaux has lost population overall in the 20th century, these suburbs have grown in some cases to ten times their original population. The expansion of the agglomeration in terms of area is particularly remarkable on the left bank of the Garonne: for decades, the city has been literally eating into the surrounding pine forest, constantly pushing a belt of currently preferred peripheral residential areas in front of it. The almost consistently low buildings also contribute to the consumption of land.
The high-density part of the conurbation lies roughly within the ring road. The intersections between the ring-shaped boulevard and the arterial roads are the so-called barrières. Far from forming clear boundaries between Bordeaux and the suburbs, these have, on the contrary, become small secondary centres of the city centre due to their traffic situation, one half of which is located in Bordeaux, the other partly already in the neighbouring municipalities, which also each have their own city centres. These towns have populations of between 10,000 and 70,000 inhabitants.
Outside these cities or beyond the motorway ring road, the development becomes looser, the population density lower and the average income of the inhabitants higher. A few large facilities such as airports and industrial settlements break up the uniform picture. The municipalities located in this outer belt register between 5,000 and 25,000 inhabitants. On the opposite side of the Garonne, the transition is abrupt due to the smaller amount of space available. While near the city limits in Lormont and Cenon there are high-rise buildings on a large scale, immediately to the east the rural area already begins.
flora and fauna
Almost 90 % of the urban area has been densified to such an extent that there is no space left for natural habitats. Here, vegetation is limited to parks, green strips and empty building land. The fauna also exists only to the extent that it can adapt to almost completely built-up areas. Bordeaux in particular has a massive problem with its rat population, which the city administration has been combating for years by improving waste disposal and tighter control of catering establishments.
Near-natural space is found in the extreme north of the urban area and sporadically on the banks of the Garonne opposite the old town. Particularly in the north, which has been designated as a recreational area, some areas have been deliberately left uncultivated, so that flora and fauna typical of the Gironde still exist here: a number of migratory birds have their resting places here, some species of small game can be found in the woods and wetland dwellers (amphibians, etc.) can also be found in marshy areas.
The vineyards are a biotope in their own right, although they have disappeared from the Bordeaux urban area. In some neighbouring towns such as Pessac or Villenave-d'Ornon, however, vines are cultivated. Here, partridges and rabbits as well as their predators (birds of prey, etc.) have their habitats. The aquatic habitat is relatively undisturbed. In the Garonne exists a variety of organisms that have adapted to conditions in brackish water reservoirs, see Gironde. The artificially created lakes are mainly inhabited by ornamental or angler fish.
