The first written mention of Manětín is from 1169, when King Vladislaus II donated the settlement to the order of Knights Hospitaller.

From a legal point of view, the town belonged to the Knights Hospitaller until 1483, when the Švamberks paid them off.

During the Thirty Years' War, internal disputes took place in the town and owners changed rapidly.

Immediately after the fire, Václav Josef Lažanský had completely rebuilt the castle according to the plans by Jan Santini Aichel.

The valuable church complex includes the rectory, the enclosure wall with two gates, and statues and crosses.

In a small area, there are many monuments: the ruins of the Sychrov Castle from the 14th century, the Baroque castle from 1705, the town fortifications from the first half of the 13th century, the Servite monastery from 1672 with the adjacent Church of Our Lady of Seven Sorrows, a group of folk houses with timber and half-timbered architecture, and a stone bridge.
