Loona Manor
An estate has existed on this location at least since 1480 and the original building was a fortified manor house. This so-called "vassal castle" was destroyed at the beginning of the 17th century (Purtse Castle in eastern Estonia is a surviving example of the same type of building). The present building dates from 1785 and has been rebuilt at different times since then. During the Soviet occupation of Estonia, the building fell into disrepair. It was renovated in 1997.
