Hermann Oberth Memorial House

Built in Gothic style in 1444, this church was later renovated in baroque style and a rococo style altar was added. The annex once served as silversmiths' workshops.

The fortified-church was built in Gothic style in 1488, with time it went through different modifications. The feeble ground structure made its tower, built in 1460, incline. 1550 the church was raised with three storeys and in 1551 four smaller towers were added to show that the city had a court. It was at that time that it gained its 68.5 meters height. In 1783 the roof-structure was changed and the small towers renovated, it was also than that the golden globe, dating from 1550, was brought down from the tower and according to tradition its content was read aloud.

So called because guards would search the horizon and sound an alarm by trumpet to warn people against enemy attack or fire, was added to the citadel's defense system in the 13th century. In 1880, a huge clock, showing the phases of the moon was set up in the tower. This tower proved to be a good spotting post. In those times the trumpeter in the tower had a great function, alerting about the approaching danger. If he made a mistake, he would've been thrown out from the top of the tower.

It was in this house that historian Stephan Ludwig Roth (1796-1849) was born. Roth challenged the 1884 Magyar Diet’s decision imposing Hungarian as the official language in Transylvania. As Romanians made up the bulk of the population, Roth claimed that Romanian was justified to be the official language. His progressive ideas led to his assassination in May 11, 1849.
