The Dominican monastery was founded in 1246 and it is the oldest one in the medieval old town. The center of monastery was St. Catherine's Church, which was completed in the late 1300s and was the largest church building in the lower town. The Monastery was expanded several times, most recently in the 16th century.
St. Catherine's convent closed down in 1525, when the monks were expelled from Tallinn during the Reformation. The looted and empty monastery church was destroyed by fire in 1531 - only ruins were left.
There were originally three inner chambers (together so-called claustrum) in the monastery allowed only for residents. The claustrum housed the most important rooms in the monastery: the prior’s room, the old library, the chapter hall, the dormitory, the sacristy, the cloister and the vestry. In the 14th and 15th centuries the leaders of the knight guilds of Harju and Virumaa often used the claustrum as their meeting and gathering place.
Only the eastern chamber has been preserved to our days. The dormitory, library, dining room and other rooms provide a fascinating opportunity to take a peek into the life of medieval monks. A mysterious "energy column" is located in the basement. According the legend it can be a source of physical and mental well-being.
Thanks for the comment, the photo is changed now!
The middle photo does not depict the Dominican Monastery. It shows the Tallinn townwall with two defencetowers, Maidentower (Neitritorn) and Kiek in de Kök. The photo was taken from the Danish King`s Garden. The monastery is about 7 minutes walk from there :).
Medvedgrad is a medieval fortified town located on the south slopes of Medvednica mountain, approximately halfway from the Croatian capital Zagreb to the mountain top Sljeme. For defensive purposes it was built on a hill, Mali Plazur, that is a spur of the main ridge of the mountain that overlooks the city. On a clear day the castle can be seen from far away, especially the high main tower. Below the main tower of the castle is Oltar Domovine (Altar of the homeland) which is dedicated to Croatian soldiers killed in the Croatian War of Independence.
In 1242, Mongols invaded Zagreb. The city was destroyed and burned to the ground. This prompted the building of Medvedgrad. Encouraged by Pope Innocent IV, Philip Türje, bishop of Zagreb, built the fortress between 1249 and 1254. It was later owned by bans of Slavonia. Notable Croatian and Hungarian poet and ban of Slavonia Janus Pannonius (Ivan Česmički) died in the Medvedgrad castle on March 27, 1472.
The last Medvedgrad owners and inhabitants was the Gregorijanec family, who gained possession of Medvedgrad in 1562. In 1574, the walls of Medvedgrad were reinforced, but after the 1590 Neulengbach earthquake, the fortress was heavily damaged and ultimately abandoned. It remained in ruins until the late 20th century, when it was partly restored and now offers a panoramic view of the city from an altitude of over 500 meters.
