The Hide

Colchester Zoo has been open since 1963 and is home to many rare and endangered species, including big cats, primates, birds, invertebrates and fish. The animals are arranged in themed zones, so you move from one habitat to the next as you explore.

Tip: Arrive close to opening, and book e-tickets online at least 24 hours ahead to get the cheaper rate. If you arrive after midday, visit Kingdom of the Wild and Elephant Kingdom first, as they close an hour early.

Colchester Castle is a Norman castle dating from the second half of the eleventh century. Its keep is mostly intact and is the largest of its kind anywhere in Europe. The Normans built it on the foundations of the Roman Temple of Claudius, the largest Roman temple in Britain, so Roman and medieval history sit together in one building.

Layer Marney Tower is a Grade I listed early Tudor house in Essex, built in rich red brick with some of the finest Italianate terracotta in the country. Its gatehouse is the tallest Tudor example in Britain, and it was begun by Henry, 1st Lord Marney, who served Henry VIII as Lord Privy Seal.

Hedingham Castle sits on a hill above the village of Castle Hedingham in Essex. Its Norman keep was built around 1140 by the de Vere family, later Earls of Oxford, and is widely described as the best preserved of its kind in England. The estate is still a family home, owned by their descendants, the Lindsays.

Tip: Download the free Bloomberg Connects guide before you go, as the Mansion has no Wi-Fi, and note there is no parking at the museum.
