The first written record of the Blankenfelde manor dates from 1689 when the owner was Ernst von Medem. The estate changed owners several times and was part of the von Hahnide family from 1840 until 1920. Between 1804 and 1805 the manor belonged to the Russian imperial house of Andreas von Königfelsile. Louis XVIII, King of France, lived in Blankenfelde manor for a while when he was in exile.
The complex structure of the manor dates from the mid 18th century, and the main building erected in 1743 has a 19th-century English-style park. There are currently ideas for the exploration of the estate in the concept of private ownership and tourism. The renovation work of the main building is now underway. Blankenfelde estate flower garden is part of the spring tulbifestivale.
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.
