- The construction of Pirita Abbey was started in 1407, which was a busy time in construction of Tallinn The initiative for the abbey came from the rich merchants in the town. The convent, which was the first building in the area, followed the rules and codes of the St. Brigittines and the main convent was located in Sweden.

- The modest construction was started to expand in 1417. In 1436 the construction of the church was completed, which still is the most visible part of the ruins.

- The abbey functioned for 140 years, until to the year 1577. During that year, as a result of the Livonian War between Russia and the Old Livonia, the Russian troops occupied the town and destroyed the abbey completely. After this devastation, the abbey was never again restored as the reformation had already reduced the significance of the abbey.

- However in the 17th century a cemetery was established to the area, from where the graves are still visible, even when most of the crosses on the graves date from the 19th century.

- Today, there's again convent working beside the ruins. In the year 2000, the Brigittines began to build a new convent and the construction was completed in 2001. The complex which is visible from the ruins, consists a chapel, guest house and a cloister. From the ruins, only the the main walls of the church still stand and from the living quarters, only the foundations remain. Still, it's a very beautiful place, even during the thaw.

- The main entrance to the church, which is strangely pointing towards west. Usually all of the entrances to the Brigittine churches, were pointing towards east, but the church of Pirita Abbey is an exception. Most likely this is because even some 600 years ago, the main road was traveling on the west side and on the east side of the church, there is a river.

- The entrance to the cloister, which actually leads you to the cemetery, which was taken into use, after the Abbey had been ruined by the Russian troops.
