This Beacon Hill alleyway entrance to multiple townhouses is marked "No Trespassing," so I let my camera do the dirty work.
Spring Lane is no named because this spot had a great hand in the genesis of today's Boston. Original settlers in the area that is now Charlestown became ill due to poor water quality. Word spread of a pristine spring in the Shawmut peninsula, so began a slow migration and development here to what was then an island connected by a causeway. The spring that fed here was the main source of water for more than 200 years.
Historic Scott Alley is one of those 18th-century impossibly narrow passageways. This one near Quincy Market led to Creek Square (said "creek" being Mill Creek, which was dug between the Town Cove and the Mill Pond in 1643).
