Koroinen was the residence of Bishop of Finland between years 1229 and 1300. in 1300 the bishop seat was moved couple of kilometres further down the River Aura, to the present-day Cathedral of Turku. There were at least two wooden churches in Koroinen built in the 14th century. The latest one was probably a stone church. It was later destroyed by the Victual Brothers in 1396.
Archaeologists have found remains of three wall grounds, which were probably part of the church. Today there are a white, wooden memorial cross and some stone foundations still remaining on site. The landscape of the site is anyway unique in Finland. You can see three medieval church from there: The Turku Cathedral, St Mary's Church and St. Catherine's Church.
Fisherman's Bastion is a terrace in neo-Gothic and neo-Romanesque style situated on the Buda bank of the Danube, on the Castle hill in Budapest, around Matthias Church. It was designed and built between 1895 and 1902 on the plans of Frigyes Schulek. Construction of the bastion destabilised the foundations of the neighbouring 13th century Dominican Church which had to be pulled down. Between 1947–48, the son of Frigyes Schulek, János Schulek, conducted the other restoration project after its near destruction during World War II.
From the towers and the terrace a panoramic view exists of Danube, Margaret Island, Pest to the east and the Gellért Hill.
Its seven towers represent the seven Magyar tribes that settled in the Carpathian Basin in 896.
The Bastion takes its name from the guild of fishermen that was responsible for defending this stretch of the city walls in the Middle Ages. It is a viewing terrace, with many stairs and walking paths.
A bronze statue of Stephen I of Hungary mounted on a horse, erected in 1906, can be seen between the Bastion and the Matthias Church. The pedestal was made by Alajos Stróbl, based on the plans of Frigyes Schulek, in Neo-Romanesque style, with episodes illustrating the King's life.
