The chapel in Saha used to be one of the oldest ecclesiastical centres of Rävala Maakond (Shire). Originally, Saha Church was made of wood, it was burnt down around 1223. Four cult stones with small hollows dating from the 1st millennium BC, located close to the chapel indicate that it had been an ancient cult place. The current chapel was built by builders from Tallinn in the second quarter of the 15th century.
Structurally, the chapel bears striking similarities to Pirita Klooster. This simple double-vaulted parallelogram-shaped buiding is slightly asymetrical. Several construction details, like very high placed windows, a corner tower, a high gable roof etc., show that in addition to serving as the house of god, the Chapel had other functions as well. In case of necessity it could become a fortified stronghold protecting against enemy attacks, a resting place for pilgrims or a storage room for merchants. The chapel was badly damaged during the Great Northern War and was restored as recently as 1962-1969.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
