Church ruins Virgilienberg

South of Friesach in Carinthia, Austria, stands the church ruin of Virgilienberg, once a fortified provostry with a church.
History+
The consecration of the church, named after Saint Virgil, took place no earlier than after his canonization in 1232. As early as 1240, Hartwig is documented as the first provost of the complex. In the second half of the 13th century, the provosts took over the vice-dominate. The provostry housed a library of European renown. In 1309, the complex was first ravaged by fire, with the visible walls today originating from the subsequent reconstruction. In 1606, the provostry was dissolved. After another fire in 1752, only the choir of the church was re-roofed in 1754. In 1786, the church was secularized, and after a final fire in 1816, its decay began. Despite preservation efforts starting in 1894, the triumphal arch collapsed in 1926.
