Haštalské náměstí 1041/6

Baroque mural, Prague

The Square of St Castulus (sv. Haštal), a quiet backwater of Prague’s Old Town, contains several notable buildings, including a Baroque-period ossuary (bone-house) dedicated to the Holy Trinity, on whose south-facing wall this fresco appears.

The fragment reads ‘[Sum]ma Trini[tas] Miserere No[bis]’: ‘May the Holy Trinity have Mercy on Us’.
