On Saturday, we asked readers to identify the location of an undated historical photo taken in the Bryn Mawr-Gladwyne Patch area.
Today, the answer: According to the Lower Merion Historical Society, it's the former Gladwyne Colony mental health facility on Mill Creek Road in Gladwyne.
Check next week for another mystery historical location, and email brynmawr@patch.com to suggest a place in Bryn Mawr, Gladwyne, Villanova or Rosemont we can use in this feature at another time.
