Our View

Knocking Hoe NNR is an area of species-rich chalk grassland near the village of Pegsdon at the northern end of the Chilterns. The site is of exceptional importance because it supports large populations of a number of rare plants. The star rarities at Knocking Hoe include: moon carrot, spotted catsear, field fleawort, burnt tip orchid and Pasque flower. The site is also of archaeological interest, with a prominent strip lynchet field system, dating from the Middle Ages, on the slopes of the hill. In summer, colourful wildflowers cover the chalk grassland, including horseshoe vetch, small scabious, rock rose and clustered bellflower. The site is also well known for its population of the orchid autumn lady’s tresses, which has been studied continuously on the reserve for 50 years. Various downland butterflies can be seen at Knocking Hoe in summer, including the common blue, chalkhill blue and brown argus.

About the area

Discover Hertfordshire

As Hertfordshire is so close to London, many of its towns have become commuter havens. St Albans, less than 19 miles (30km) from the capital, has retained its distinctive character, along with many historic remains. The Roman city of Verulamium is situated in a nearby park, and excavations have revealed an amphitheatre, a temple, parts of the city walls and some house foundations. There are also some amazing mosaic pavements.

The abbey church at St Albans is thought to have been built on the same site where St Alban met his martyrdom in the 3rd century. The abbey was founded in 793 by King Offa of Mercia, and contains the saint’s shrine, made of Purbeck marble. Lost for years, it was discovered in the 19th century, in pieces, and restored by the designer of the red telephone box, Sir Giles Gilbert Scott. The abbey also contains some wonderful medieval wall paintings. Nicholas Breakspear was born in St Albans, the son of an abbey tenant. In 1154 he took the name Adrian IV, and became the first, and so far only, English pope. Another famous son of Hertfordshire was Sir Francis Bacon, Elizabethan scholar and Lord High Chancellor, born in Hemel Hempstead in 1561.
