Occidental Park and Occidental Square are adjacent open spaces in Seattle's Pioneer Square District. Despite significant attention from the city, they have been, well, troubled areas for years. There was a brief renaissance during which Occidental Square became a thriving gallery district -- nearly every building opening onto the square was a gallery except for an excellent coffe shop on the corner of Dearborn.
The "first Thursday" art walk was thronged with visitors, there was music on adjoining Occidental Park, and a good time was definitely had by all. I did a short term project on Occidental Square and it was shown in the now-closed Market Photo gallery near 1st and Pike.
Alas, almost all the gallerys have all fled to be replaced by offices.
