In spring, the woods fill with the scent and colour of bluebells and anemones.

The famous and much-loved Gruffalo trail also starts here. Pick up a trail in the Countryside Centre for a small price before you start, and enjoy a refreshing drink from the cafe when you've found all the characters.

Cycling is also a great way to experience all that this beautiful park has to offer: the north of the park with its wildlife-rich woodlands and the south with its open parkland.

Thorndon Country Park was once part of the estate owned by the Lords Petre. Originally emparked in 1414 around the old Thorndon Hall, it has a rich landscape history.

Reimagining historic features include Old Hall ruins, Pigeon Mount and earthworks of The Menagerie.

This centuries-old park includes diverse and ancient habitats, and is home to some important veteran trees, woods and pasture.

The Essex Record Office traces the history of the old Thorndon Hall

Thorndon Hall is situated in Ingrave, about two miles south of Brentwood. The present building is a grand neo-classical mansion in the Palladian style, completed in 1770. It was designed by the eminent architect James Paine, with interiors by Samuel Wyatt. The gardens were later landscaped by Lancelot ‘Capability’ Brown.

This was not, however, the first grand house to grace the estate. Lewis John, a Welsh merchant who had moved to London, acquired the manor in the early 1400s and in 1414 Henry V granted him a licence to augment his existing house with crenellations, and to build a wall enclosing 300 acres of land and wood.

This house was later extended, before the property was sold to Sir John Petre in 1573. Sir John’s father, Sir William Petre, had held high office under Henry VIII, Edward VI, Mary Tudor and Elizabeth I. He had established the family at Ingatestone Hall, which he had left to his wife after his death. Sir John, therefore, was looking for a property of his own.

Over the next 20 years, Sir John made extensive alterations and additions to Thorndon Hall, turning it into a classic Elizabethan red-brick mansion. This is the house we see on a map of 1598 made by the skilled cartographer John Walker, with the 270-foot long mansion, detached L-shaped bakehouse and clocktower, stable block, pleasure gardens, orchard and gatehouse.

Just over a 100 years later, the 8th Baron Petre, Robert, made grand plans to redesign the hall with the help of Venetian architect Giacomo Leoni. The extensive plans included re-facing the hall in a symmetrical, neo-classical style, covering over the Elizabethan exterior.

Petre was also a keen botanist and in 1733 he engaged Sieur Bourginioni to draw up plans to re-landscape the estate, including designing a water garden. He also imported many foreign plants and built hot houses, successfully cultivating exotic species such as pineapples and bananas.

Robert Petre died suddenly, aged just 29, before his plans were completed. His son and heir was just a few months old and all further work was put on hold until he reached maturity. As an adult, the 9th Baron decided to build a brand new house, a mile away from the old hall. This is the Palladian mansion which we see today.

The new house cost more than £250,000 and took six years to build. Between 1766 and 1772, Capability Brown was employed to reshape the formal gardens into a more ‘natural’ looking landscape.

The main house and west wing were gutted by fire in 1878 and family finances did not permit a wholesale renovation. Eventually the property was sold. Today the house has been converted into apartments and the grounds contain golf courses. Much of the park is managed by Essex County Council as Thorndon Country Park.
