Hajnáčka castle was built in the Gothic style against the Mongol invasion in the mid-1200s. Later, in the mid-15th century, the construction was finished. Hajnáčka was the seat of important feudal lords. In 1545 the castle was besieged and conquered by Ottomans. At the end of the 16th century and the first third of the 17th century castle was an important part of the anti-Turkish defensive line. Nevertheless, it Turks in 1645 again briefly occupied for few years. In the 17th century the castle was only partially inhabitated. In 1703 it was burnt down and no longer restored.
Today the remains of walls stand on the top of the hill which is hard to reach.
References:The church of the former Franciscan monastery was built probably between 1515 and 1520. It is located in the UNESCO World Heritage Site of Old Rauma. The church stands by the small stream of Raumanjoki (Rauma river).
The exact age of the Church of the Holy Cross is unknown, but it was built to serve as the monastery church of the Rauma Franciscan Friary. The monastery had been established in the early 15th century and a wooden church was built on this location around the year 1420.
The Church of the Holy Cross served the monastery until 1538, when it was abandoned for a hundred years as the Franciscan friary was disbanded in the Swedish Reformation. The church was re-established as a Lutheran church in 1640, when the nearby Church of the Holy Trinity was destroyed by fire.
The choir of the two-aisle grey granite church features medieval murals and frescoes. The white steeple of the church was built in 1816 and has served as a landmark for seafarers.
