Bolsward (West Frisian: Boalsert) is a municipality and a city in the province of Friesland in the Netherlands. Bolsward is just short of a population of 10.000. The town is the only official settlement within the borders of the municipality
The town is founded on three artificial dwelling hills, of which the first was built some time before Christ. Bolsward was a trading city with a port in the Middle Ages. The middlesea connected the port to the north sea, but this connection was lost when the middlesea was reclaimed from the sea. As a trading city, Bolsward received city rights in 1455. Bolsward was also a member of the Hanseatic league.
Bolsward is also the host city for the yearly road bicycle racing tour, which is also called the 11-stedentocht.
