Site Event/Activity record ECH4033 - Archaeological Observations During Works to Enhance Visitor Access at Halton Castle

Archaeological watching brief undertaken in July 2006 during the installation of a new fence at Halton Castle, within the Scheduled area. Most of the post holes excavated for the fence proved to be cut into very recent backfill associated with the reconsolidation of the castle wall in the 1990s. The only exceptions to this were at the northern end of the new fence where, in post hole 28, mortar-bonded rubble foundations were seen set directly onto bed rock, these are thought to represent the original medieval foundation. Also, at the southern end of the fence line, in the pit for post 43, ashlar sandstone blocks were exposed and probably represent the foundations of a nineteenth century folly. (1)
