Situated in the shelter of Mount's Bay & St Michaels Mount, Penzance has a temperate climate, milder than most of the rest of Britain. Penzance (Pensans), or "holy headland" in the Cornish language, is a reference to the location of a chapel nowadays called St Anthony's that is said to have stood over a thousand years ago on the headland to the west of what became Penzance Harbour.
Approximately 400 prehistoric stone axes, known as Group 1 axes and made from greenstone, have been found all over Britain, which from petrological analysis appear to come from West Cornwall. The quarry has not been identified, but it has been suggested that the Gear, a rock now submerged half a mile from the shore at Penzance, may be the site. Chysauster, an English Heritage site, is also worth a look.
