Danesbury Fernery in Welwyn, Herts, was built by the famous Pulham Company of Broxbourne in 1859, originally in the grounds of nearby Danesbury House. It consists of a cave and water feature, made of artificial stone, ‘Pulhamite’. It was built in what was originally a chalk pit, and surrounded by a fernery. After falling into disrepair, the fernery was restored by the Friends of Danesbury Fernery from 2015 onwards and is a wonderful place to visit at any time of year.
