I spotted this flight of stone steps in Falmouth and was intrigued to know where they led. Some research reveals that they are known as Jacob's Ladder and comprise 111 steps.
After a brisk climb they ascend to a terraced lane which runs parallel to and above the main shopping street with fantastic views aover the harbour and right across Carric Roads.
On the decent back down to the town, above the Church of King Charles the Martyr was this stone crypt, adjacent to what was once the old town mortuary, now converted to a family home.
There's a nice tour of the town including the steps on Youtube by Cornish Walking Tours which includes teh same route and lots more history, worth a watch.
