This brick-paved triangle with an often-dry fountain awkwardly commemorates the signing of the UN charter in San Francisco. At best in broad daylight, UN Plaza offers clear views of City Hall, skateboarders attempting fountain flips, Scientologists drumming up converts and the odd drug deal in progress. The wonderful Heart of the City Farmers Market provides a fresher perspective on the Tenderloin, and Pride, Tet (Vietnamese lunar new year) and other community celebrations bring signs of life to grim UN Plaza.
