Holywell is a tiny settlement in the civil parish of Careby Aunby and Holywell, in the South Kesteven district of Lincolnshire, England. It lies 5.5 miles (9 km) north from Stamford and 6 miles (10 km) south-west from Bourne. It is a collection of houses around a country house and park. The park includes a small private church dedicated to St Wilfrid. Ornamental lakes have been restored over the last 20 years, and new gardens laid out. In 2009 the gardens were open to the public through the National Garden Scheme.
