The Weighing House was built in 1660s as a place to keep the public scales, while the central square served as the market place. This is the only building of its type that has survived in Estonia. The main attraction of the small two story limestone building is in the strict symmetry in the architecture and the scaled gable, decorating the façade. The Weighing House was enlarged with a single story building in the 18th Century, probably for stables.
The building has had numerous functions throughout the centuries. At the turn of the 18th century, it accommodated the Town Guard, at the turn of the 19th, the Town Post Station. The initial façade was restored in 1980 - 1982, by the architect, L. Hansar, and the historian, A. M. Hallik.
The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
