Nanceglos Well, Trengwainton

## Overview Nanceglos Well is a historic public drinking spring located on the grounds of Trengwainton, near Penzance in the far west of Cornwall, England. Situated at GPS coordinates 50.12692, -5.566963, this well sits within the landscape surrounding Trengwainton Garden, a celebrated National Trust property known for its exotic plantings, walled gardens, and stunning views toward Mount's Bay and the Lizard Peninsula. The name "Nanceglos" is of Cornish origin — "nans" meaning valley and "glos" (or "eglos") meaning church — suggesting a long historical connection between this water source and an early ecclesiastical site in the valley. Cornwall is renowned for its holy wells and sacred springs, many of which have been in continuous use since pre-Christian times and were later adopted by Celtic saints. While specific historical records for Nanceglos Well are scarce, its presence on the Trengwainton estate places it within a landscape that has been inhabited and cultivated for centuries. The Trengwainton estate itself dates back to at least the 16th century and has passed through several notable Cornish families. The well has historically been used as a source of drinking water by locals and visitors alike, though as with any natural water source, conditions can vary and water quality cannot be guaranteed. ## What to Expect Nanceglos Well is found in the lush, sheltered landscape near Trengwainton Garden, an area characterised by mature woodland, subtropical plantings, and the gentle terrain of the valley leading toward Madron and Penzance. The mild, frost-free microclimate of this part of West Cornwall supports an extraordinary range of plant life, and the surroundings of the well reflect this verdant character. Visitors should be aware that the well is a traditional Cornish spring — expect a modest stone or granite structure rather than a grand monument. Water flow may vary seasonally, with the wettest months (autumn and winter) typically producing the strongest flow. The area can be muddy, particularly after rain, so sturdy footwear is recommended. The nearby Trengwainton Garden (managed by the National Trust) is well worth a visit and offers car parking, paths, and facilities. The garden is typically open from February through October, though the surrounding landscape and public footpaths may be accessible year-round. The well's location in the Cornish countryside means mobile phone signal can be patchy, so it's wise to note directions before setting out.
