Helliden Castle, Manor house in Tidaholm Municipality, Sweden.

Helliden is a manor house on the western slope of Hellidsberget, built in 1858 by Baron Hans Henric von Essen. It was enlarged into a castle-like residence by his son Alfred von Essen, with architect Helgo Zettervall. Since 1951 it has housed Helliden Folk High School.

Hans Henrik von Essen built the original manor house in 1858 while managing Tidaholms bruk, a facility for manufacturing wagons and farm equipment. It was later converted into a folk high school residence and has served educational purposes ever since.

Helliden takes its name from Hellidsberget, the hill on whose western slope it stands. Since 1951 the estate has belonged to the Blåbandsrörelsen (Blue Ribbon movement), which opened a folk high school here; the first winter course began in 1952 with 32 students. In the 1930s the manor had already received city children for country stays, among them the writer Lars Forssell.

The castle sits near exercise and skiing trails on the Hellidsberget mountain, making it a good starting point for outdoor activities. Visitors should note that accessibility varies by season, especially when snow affects hiking paths.

Alfred von Essen, who gave the manor its present castle-like form with architect Helgo Zettervall, went bankrupt after the Kreuger Crash; everything was sold except the main building, where Baroness Ella von Essen lived until her death in 1950. In the 1930s city children, among them the writer Lars Forssell, were invited to stay at Helliden.
