English: Prospect Place. Looking along Prospect Place towards East End Road. The bridge over the Northern Line has long since been closed to road traffic. The houses on the right are in Oakview Gardens. The two thin poles visible at the opposite end of the bridge are eruv markers. An eruv is a contiguous boundary denoted by string or natural markers (such as in this case, the Northern Line) that enables Orthodox Jews to carry items or push baby strollers within its borders during the Sabbath. The string between the poles is too thin to show in the photo.
