We have just returned from a visit to friends whose garden is the site of a large house that burnt down in the early 20th century. Dry weather (not this year obviously) revealed the outline of many walls lying just below the lawn surface. Various exploratory digs have uncovered the remains of the cellars with much of the structure intact. They are gradually creating a series of sunken gardens which are only revealed as you walk across the lawn. They are both quirky and lovely. Excavations continue.
