The street sign at the corner of Abbey Rd and Grove End Rd. The zebra crossing is to the left and a bit north a few yards. The intersection includes a small island in the center with a column/statue pedestal. It was from there that the cover of the Abbey Rd album was shot.
Abbey Rd is a very busy street; I was honked at mercilessly as I fooled around in the crosswalk while I had some other tourists took a photo of me.
