Holy Trinity Church, Baroque church in Nové Město, Prague, Czech Republic

Holy Trinity Church is a High Baroque building on a nearly square plan, facing Spálená Street, with a tower above the presbytery and a two-storey entrance facade divided vertically into three parts. Above the main door are the oval cartouches with the coats of arms of donors Jan Ignác Putz of Adlersthurn and his wife Terezie Klára, and a gilded Latin dedication, SANCTISSIMÆ AC DIVINÆ TRINITATI. The second storey's side axes end in volute wings, with statues of St John of Matha and St Felix of Valois.

Construction started in 1708 under architect Octavian Broggio, with master builders Kryštof Dientzenhofer and Jan Jiří Aichbauer overseeing the work. Their collaborative effort shaped the baroque character that defines the building today.

Since February 2006 the church has served Prague's Slovak Greek Catholic community, after the local Roman Catholic parish was dissolved at the end of 2005. The building is protected as a cultural monument and stands next to the Faculty of Education of Charles University.

The church stands on Spálená Street, next to the Pedagogical Faculty of Charles University; the former convent building toward Lazarská Street was demolished in 1889. Since February 2006 it has served the Slovak Greek Catholic community in Prague, so services follow the Greek Catholic rite rather than the Roman one.

Above the main entrance are the convex oval cartouches with the coats of arms of the donors Jan Ignác Putz of Adlersthurn and his wife Terezie Klára, with a Latin dedication naming them as founders. Higher, under the cornice, gilded letters read SANCTISSIMÆ AC DIVINÆ TRINITATI.
