Green Dome Garden in located in McCarren Park (Williamsburg, Brooklyn), and is just a few blocks from both subway and bus stops. This community garden is unique in that it is open daily (from 9 AM till dusk) without an attendant. North 12th (between Driggs and Union Aves)
In order for a public space to be great - you must have access.
Green Dome garden is especially popular with people who use McCarren Park regularly; There are several benches, the most prized being a beautifully crafted dome shaped bench. Overtime the paths have been paved with Belgium blocks to improve access for the elderly, baby carriages and wheelchairs. Alternatively some areas have stepping stone paths which are accessible only by foot. (source: http://www.pps.org/great_public_spaces/one?public_place_id=348
