Berkeley Castle in Gloucestershire began as a Norman motte-and-bailey around 1067 and was rebuilt in stone through the 12th and 14th centuries. It has a circular shell keep, a curtain wall, Thorpe's Tower and an inner gatehouse. The Berkeley family have held it since the 12th century, apart from a spell of royal ownership under the Tudors.

SS Great Britain is a museum ship on Bristol's harbourside, designed by Isambard Kingdom Brunel. When launched in 1843 she was the largest passenger ship in the world, and one of the first iron, propeller-driven ocean liners.

Tip: Parking is available at the Maritime Heritage Centre car park next to the site, and you pay at the ticket desks. The Long Ashton Park & Ride is an alternative Monday to Saturday.}

Aerospace Bristol sits on Filton Airfield, in a First World War Grade II listed hangar and a purpose-built Concorde hangar. The galleries trace over 100 years of aviation history, from the early pioneers through two world wars and the space race to today's aerospace industry, with exhibits from model aircraft to helicopters, rockets and missiles.

Tip: Allow at least three hours, and head for Concorde and its projection show first.

Newark Park is a National Trust property near Wotton-under-Edge. It began as a Tudor hunting lodge, built in the 16th century, and is now a Grade I listed house. It sits at the southern end of the Cotswold escarpment, with views down the Severn Valley to the Severn Estuary.

Tip: Don't rely on your SatNav, as it can send you up a very steep single-track lane. Follow the brown signs for Newark Park instead.

Dr Jenner's House, formerly the Edward Jenner Museum, is the Berkeley home of Edward Jenner, who carried out the first vaccination there in 1796. The grade II* listed house, known as the Chantry, tells the story of how vaccination began and why it still matters today.

Tip: Some parking is available in front of the house; otherwise use the free public car parks off Marybrook Street in Berkeley, a five-minute walk away.

The Jet Age Museum sits on the edge of Gloucestershire Airport, between Gloucester and Cheltenham. It tells the story of the county's aviation, from early flight to the birth of the jet age, with aircraft, engines, models and artefacts. Much of the focus is on the Gloster Aircraft Company and the development of the jet engine by Sir Frank Whittle.

Tip: Timed tickets for the Vulcan and Trident cockpits are free from the desk by the hangar doors, so book them as soon as you arrive.
