We knew there was a barn on the property thanks to historic maps of the area, however, we're not sure when it was built. There is no barn on the property in the 1813 Hales map, during which time George Ham, a clock and watch maker owned the property.
In the photo of the wall profile below, you can see the thick layer of destruction fill related to the demolition of the Pecunies House in the 1960s, full of bricks and stones, above much thinner layers of ash and dark loam.
Upon reaching the midden layer, we opened an excavation block to the east. In the photo to the right, you can see the top of the Pecunies House basement floor, which had a thin layer of green and white linoleum sitting on a gritty, compact surface. This photo also demonstrates the extent of the destruction of the mikveh walls, as mikveh bricks have become part of the fill up to two meters from the mikveh itself.
