The Admiralty Church (Swedish: Amiralitetskyrkan) is a church in Karlskrona (south-east Sweden) and belongs to the Royal Karlskrona Admiralty Parish. The church is also known as the Ulrica Pia after Ulrike Eleonora ('pia' is the feminine form of the Latin 'pius' which means 'pious'). It is located near Vallgatan in the south east of the island Trossö. Inaugurated in 1685, it is made entirely of wood, making it Sweden's largest wooden church.
