On the outskirts of Echternach is located one of the largest and richest estates of the northwestern provinces of the Roman Empire. The completely excavated manor house, measuring 118 x 62 m, was probably a palace. It had 40-70 rooms on the ground floor alone, provided with peristyles, courtyards, basins, marble facing, mosaic pavement and underfloor heating. This magnificent estate consisted of at least ten more buildings, which regularly lined up left and right of the estate wall and were discovered through aerial photographs and geophysical prospecting. Visitors can embark on inspecting the well-preserved basements, cellars and ornamental ponds of the estate, which resurrects in all its splendour thanks to numerous digital reconstructions. More than 70 medicinal and ornamental plants as well as a pergola covered with vines are displayed in a Roman garden.
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.
