Location and administrative structure
Alphen is part of the Dutch administrative landscape and belongs to the province of South Holland. It sits amid the low-lying polder landscape typical of the region, with waterways, greenhouses and small villages nearby. On 1 January 2014 the neighbouring municipalities of Boskoop and Rijnwoude were merged into Alphen aan den Rijn, expanding its territory and adding centres known for horticulture and riverine villages.

History and heritage
The town's roots are old: archaeological finds along the Oude Rijn show habitation and activity in Roman and medieval periods. Over centuries Alphen developed as a riverside settlement, with bridges and trade along the Rhine. Visitors interested in the region's past can explore reconstructed and interpretive sites that illustrate prehistoric, Roman and medieval life.

Boskoop, now part of the municipality, is internationally known for tree nurseries and woody-plant cultivation; the area’s greenhouses and plant trade contribute to the regional economy. Retail centres, professional services and local manufacturing also provide employment.
