The church tower stands at an impressive 105 metres tall and the current appearance of the Gothic church dates back to 1405-1420, when it was completely renovated.

Niguliste Museum

Since World War II, the building no longer serves as a church and no religious services are held here.

However, the interior of the church is open to visitors as it houses the Niguliste Museum, which focuses mainly on religious art from the Middle Ages to the present day.

Admission for adults is 15 eur, but discounted combination tickets are also available for other institutions in the Estonian Art Museum group.

With the Tallinn Card, admission to the museum is free.
