Church of the Holy Spirit
The Church of the Holy Spirit is the smallest medieval church in Tallinn. The first written documents mentioning the church date back to 1316. Between 1375 and 1380 several reconstructions and additions were made to the church. Originally, the church was a single-nave church, but as the congregation grew, a side nave was added. Major changes to the façade probably took place after the fire of 1433. Minor changes were also made in the 17th century when a new Baroque bell tower with two open balconies was built on top of the octagonal tower of the church, which resembles the exterior of the town hall in its appearance.
