Ferienhort am Wolfgangsee, Protected heritage school building in Sankt Gilgen, Austria.

The Ferienhort am Wolfgangsee is a holiday camp complex in Ried 1, Sankt Gilgen, built from 1910 on the site of the acquired Villa Frauenstein. Its main building, designed by architect Franz Schönthaler, is 88 m long and 42 m deep and holds a Festsaal; the grounds cover about 40 ha of forest and meadow with roughly 2 km of lake shore.

The association was constituted on 15 April 1888 in the Vienna Rathaus council chamber as a holiday scheme for needy Gymnasium pupils, initiated by the lung specialist Leopold Schrötter Ritter von Kristelli. The first camp ran 60 days in 1888 at Wildalpen in Styria for 22 pupils, followed in the 1890s by a house at Steeg on the Hallstätter See. On 24 May 1910 the Villa Frauenstein estate at the Abersee was bought, and from spring 1911 the building designed by Franz Schönthaler, 88 m long and 42 m deep, housed about 450 youths. Camps were suspended in 1915–1918 and 1938–1945.

The camp's name, Ferienhort, literally means "holiday hoard" or treasury of holidays. Its boat programme dates to 1890, when the Austro-Hungarian naval harbour command in Pola gave two naval dinghies and granted torpedo master Johann Baumgartner leave to teach the pupils to row. Camps run as Classic, Allround and Special sessions each summer.

The site lies at Ried 1 in Sankt Gilgen, on roughly 40 hectares of woodland and meadow with about two kilometres of Lake Wolfgang shoreline. The main building, 88 metres long and 42 metres deep, faces the lake. The grounds are a children's camp, not a public park, so access is limited to camp periods and arranged visits.

The facility supports families with limited means through a fund that can cover between 25 and 100 percent of participation costs. This enables many children to attend who would otherwise lack the opportunity.
