The theatre of Carei was firstly opened in October, 1907. It was built in secessionist shape, according to plans of Kopeczek Gyorgy. Since 1920, it was also used as a "moving pictures" theatre. After the second world war, its shape was transformed into more "modern" one, balconies were destroyed and new seat-kines were put into. Today, the building functions as a theater.
Carei has a long Jewish heritage. Jews arrived to the area already at the beginning of the 18th century and the first rabbi came to town in 1724. The Jewish community kept growing and before the German occupation in WWii, there were about 3,000 jews living in Carei. After the war, only about 500 (maybe a bit more) Jews remaind in Carei and most of them emigrated to Israel. According to articles I read in the net, only 3 elderly Jews remaind in Carei.
An importent monument for the Jewish life at the region is the impressive Neolog Synagogue, that was built at the end of the 19th century and kept in a pretty good shape even today. Outside the synagogue stands the marble obelisk in the memory of the victims of the holocaust.
Nowdays, the synagogue is usualy closed for visits, but its getting opened from time to time for some Jewish cultural events, so you should check it.
The tower was bulit in the end of the 19th century to supply water and electricity to the castle. Today, it can be seen at the main street of Carei, opposite to the Victoria shop.
