Antskog ironworks, one of the oldest industrial sites in Finland, was established in 1640. The heyday of Antskog was in the 17th century, when Pohja town became a center of iron manufacturing in Finland. Industrial buildings were mainly destroyed in the Greater Wrath (1714-1721) and it caused the financial downturn. The ironworks went bankrupt couple of times.
The next upswing was in the 1860s, when Antskog started to produce copper. Antskog started also a textile business in the 19th century. The industrial story ended in 1959. Today there are about 120 people living in the ironworks area. Many summer events are also held in Antskog. The ironworks area and local wooden church (built in 1766) are open to the public.
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.
