Hammersta, Manor house and medieval ruins in Ösmo socken, Sweden.
Hammersta is an estate with a manor house built in 1914 and medieval stone ruins on agricultural land near Landfjärden. The site preserves two wing buildings and several worker residences from the early 1900s, while the original main building from the 1680s was demolished.
In 1426, Nils Erengislesson gave Hammersta to his wife Katarina Knutsdotter and had a stone house built, whose ruins remain visible today. Centuries later, the estate was transformed into a modern farm complex with new buildings from the early 1900s.
The basement walls of the medieval stone house show how wealthy families lived and built during the age of knights. Visitors can see how the walls were constructed from local stone.
The site sits on open farmland and is easy to reach, but visitors should bring weather-appropriate clothing, especially if the ground is wet after rain. The best times to explore are the warmer months when the paths are drier and easier to walk.
The author August Strindberg lived in the western wing during the 1860s. This literary connection ties the place to one of Sweden's most important artistic figures.
