The Haapsalu Cathedral (first mentioned in 1279) is one of the largest single-nave churches in the Nordic and Baltic countries. It was the main church of the Bishopric of Ösel–Wiek.
During the full moon in August, you could see the eternal lover – the White Lady – in the church window.
The cathedral is also a wonderful concert venue thanks to its good acoustics.
The cathedral is the church of the St. John's congregation of the Estonian Evangelical Lutheran Church in Haapsalu.
The services are free for visitors and the church can be entered from the main entrance. At other times, you can enter the church through the Haapsalu Castle Museum with a museum ticket.
