Alphen aan den Rijn (NL)
From Stamps of the World
The municipality of Alphen aan den Rijn also includes the communities of Aarlanderveen and Zwammerdam. The town is located in what is called the 'Green Heart' of the Netherlands, which is a somewhat less densely populated centre area of the Randstad. The name "Alphen" is probably derived from the name of the Roman fort Albaniana, meaning "settlement at the white water". Its remains still lie underneath the city centre today.
