The town is founded on three artificial dwelling mounds, the first of which was built some time before Christ.
During the Middle Ages, Bolsward was a trade center and port city connected to the North Sea via the Middle Sea. This connection was lost when the Middle Sea was reclaimed to form arable land. After this, a canal was dug to the Zuiderzee.[3] The town is first mentioned in AD 725.
As a trading city, Bolsward was granted city rights by Philip the Good in 1455. Bolsward was made a member of the Hanseatic league in 1422.[3] Before being merged into the municipality of Súdwest-Fryslân, the town of Bolsward was an independent municipality.
