Keller Fountain Park is a city park in downtown Portland, Oregon, which opened in 1970. The central feature of the park is the concrete water fountain. Keller Fountain is often noted as a memorable feature of the public landscape in downtown Portland, and in 1999 was awarded a medallion from the American Society of Landscape Architects. The fountain was designed by Angela Danadjieva using inspiration from waterfalls in the Columbia River Gorge located east of Portland. (source: wikipedia)
