Many historic structures designed by Swiss-born landscape architect Paul B. Riis can be found within South Park - Allegheny County Parks and are a rich part of the heritage of this area.

The Paul Riis Legacy Preservation volunteers are a grassroots, informal, independent group of volunteers from South Park and surrounding communities.

Our mission is to play an active role in the maintenance and stewardship of the structures that Paul Riis created, and to the preservation of his legacy.

Work parties are held on the last Saturday of each month, from 9:00 a.m. to 11:00 a.m., to ensure that the existing structures are maintained and kept free of weeds, brush and other debris.  We work under the direction and guidance of the Allegheny County Park Rangers.

We welcome volunteers of any age who are interested in helping to maintain these structures. Please consider spending an hour or two with individuals who love to play in the dirt for a great cause.
