Washington Square is composed of several distinct neighborhoods and is convenient to America's most historic square mile. Washington Square West is a lively neighborhood, while east of the park is a bit more sedate. Antique Row, Pine Street between about 13th and 9th Streets, is full of interesting shops, not all of them antiques-oriented. Washington Square itself is worth a visit to see the tomb of the unknown Revolutionary War soldier. This neighborhood is a good place to see Philadelphia's native style of house, the "trinity" -- two, three, or four floors, one room per floor, connected by spiral stairs. The small streets above Pine, such as Quince Street, are lined with trinities. WalkPhiladelphia  offers several interesting tours of Wash West.
The Gayborhood is Philadelphia's gay-friendly area overlapping the officially designated Washington Square West neighborhood.

Most straight-owned Gayborhood businesses, are friendly to queer and straight alike regardless of orientation.
