The Baroque church of the Holy Trinity or commonly known as the Premonstratensian church was the site of the martyrdom of three saints in 1619. It the Middle Ages, the Royal House (a seat of the Royal Chamber), stood on the site of the present church. In 1618, at the beginning of the Counter-Reformation and the start of the Thirty Year War, The captain of the city established there a dwelling and a chapel for Jesuits in the Protestant town. Two Jesuits Melicher Grodecký, Štefan Pongrác were sent there, to work with a canon Marek Križin. On 7 September 1619, the forces of George I Rákóczi, the father of the Prince of Transylvania George II Rákóczi, stormed the castle and arrested the priests. They gave them a death sentence on charges of treason; accusing them of inviting the Polish army into Kassa. They were tortured and then beheaded that day. The execution of the priests shocked the local population, Catholics and Protestants alike.
In 1657, the Bishop of Eger, Benedict Kishdy, founded the first Košice University (Universitas Cassoviensis) close to the site. Later, the daughter-in-law of George I Rákóczi, Sofia Bathory, wife of George II Rákóczi, bought the ruins of the former Royal House with intention of building a church for the Jesuits there to make amends for the events of the Thirty Years' War. In 1681, construction on the church finished and it was opened.
On 21 July 1773, the Jesuits was expelled from the city as part of the suppression of the Society of Jesus. So in 1811, the church was given to Premonstratensians who currently administer the church.References:
Narikala is an ancient fortress overlooking Tbilisi, the capital of Georgia, and the Kura River. The fortress consists of two walled sections on a steep hill between the sulphur baths and the botanical gardens of Tbilisi. On the lower court there is the recently restored St Nicholas church. Newly built in 1996–1997, it replaces the original 13th-century church that was destroyed in a fire. The new church is of 'prescribed cross' type, having doors on three sides. The internal part of the church is decorated with the frescos showing scenes both from the Bible and history of Georgia.
The fortress was established in the 4th century and it was a Persian citadel. It was considerably expanded by the Umayyads in the 7th century and later, by king David the Builder (1089–1125). Most of extant fortifications date from the 16th and 17th centuries. In 1827, parts of the fortress were damaged by an earthquake and demolished.
