A Castle Abandoned for Want of Water

The church of Saint Gall on Havlín, formerly called Osek hill, is the remnant of an old castle, abandoned in quieter times for want of water. It belonged to the Slavník family and is said to have been the seat of Izbislav of Bivoj's line, the founder of Zbraslav. In 995 Boleslav II seized the castle and the estate.
