The Romanesque style apse of Igelösa Church was built in the 12th century. The tower and vaults were added in the 15th century. Two choirs were added in the 17th century. There are two sarcophagi in the so-called “Gyllenkrookska koret”, which is the grave of Axel Gyllenkrook and his wife. The current appearance dates from 1859, when the church was restored by the design of C. G. Brunius. The altarpiece and pulpit were moved to the church in 1732. The baptismal font dates from the original church.
References: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.
