While surfing the internet in general for items about Newhaven, I came across a site whose members specialise in locating and exploring tunnels throught the UK. Apart from the obvious one of HMS Forward at South Heighton which was mentioned on the site, the name Saxonholme is also mentioned as having a tunnel. The following information is taken from the website www.chelseaaspelaeo.org.uk
"Apparently a local rumour had it that a tunnel ran from the house to the Convent so in February 1977 two members of the Society persuaded the owner of Saxonholme to let them look and they actually gained access to the tunnel from an opening in the cellar. The tunnel was about 8m long with walls of stone, while the floor and the vaulted ceiling were brick. At the far end was a well, capped at floor level. A shaft ran upwards from the well and emerged in the middle of the garden above, where it was covered with a large stone slab. It is thought that the tunnel was constructed so that water could be carried from the well to the house without the need to go through the garden."
Was anybody in Newhaven aware of the existence of the cellar/Tunnel/Well during the demolition of the building, or did it just disappear under a pile of brick rubble I wonder?
