Jollas is a southeastern neighborhood of about 3000 people in Helsinki, Finland located in the eastern part of the Laajasalo island.
Jollas was for a long time a loose single-family area with old wooden houses, but since the 1980s the area has been more densely built up.
The history of Jollas begins with the Jollas Manor in 1798. The present main building of the manor dates back to 1919 and was designed by Robert Tikkanen.
Nature.
The nature of Jollas represents the inland Archipelago zone of southern Finland with its rocky and sandy terrain, dry cliffs and lush marshes. There are traces of the Ice Age in Tonttuvuori with a double -giant's kettle. There is also a small four-hectare nature reserve called Jollaksen räme near Furuvik beach.
