Trinity Church, Baroque church on Stortorget in Karlskrona, Sweden

The Trinity Church is an octagonal Baroque church on Stortorget in Karlskrona, designed by Nicodemus Tessin the Younger. Its copper-green ribbed dome, topped by a lantern and cross, rises above orange walls with rectangular panels. A portico with four smooth grey columns and a triangular pediment faces the square, and stone steps lead to the entrance.

German-speaking residents of Karlskrona, founded in 1680, received royal permission on 17 October 1689 to form their own congregation. The first foundation stone was laid on 3 June 1697 to designs by Nicodemus Tessin the Younger, and the church was inaugurated on 27 June 1709; work continued for another 40 years. After the town fire of 1790 only the walls remained, and Olof Tempelman rebuilt it in Neoclassical style, re-inaugurated in 1802.

The church is also called the German Church, as it served the German-speaking congregation founded in 1689, which merged into the Karlskrona city parish in 1847. Inside, the pulpit in Empire style has a sculpted drapery and a canopy carried by two slender columns, and it encloses the sacristy. The pews are closed, with rectangular panels.

The church is open for visits on several days each week, and the bright interior makes it easy to explore the architecture and furnishings. Visitors should keep in mind that access may be limited during religious services or special events.

The organ built in 1827 by Pehr Zacharias Strand, with 20 stops and a facade by Carl-Gustaf Blom-Carlsson, is the largest surviving instrument by this builder and one of the best preserved. Its predecessor, a 1737 organ by Gottlieb Richter of Stralsund, burned with most of the furnishings in 1790. A small four-stop choir organ by August Laukhuff, moved here from the Fredrik Church in 2015, stands in the chancel.
