A short hop from central London by tube but a world apart. Stroll up the tree-lined drive, past the grazing Charolais cattle and you'd think you're in the country, not urban Hounslow.

Surrounded by gardens, park and farmland, Osterley is one of the last surviving country estates in London.

Once described by Horace Walpole as 'the palace of palaces', Osterley was created in the late 18th century by architect and designer Robert Adam for the Child family to entertain and impress their friends and clients.

Originally 5 metres (16 feet) high and weighing some 16.75 tonnes, this is Cornwall's largest and heaviest prehistoric monolith. 

This massive stone stands near the summit of the St Breock Downs, offering beautiful views of the surrounding countryside and across to the sea.

It is the largest and heaviest monolith in Cornwall, weighing in at about 16.5 tons (16.75 tonnes), and probably dates to the Late Neolithic to mid-Bronze Age (around 2500–1500 BC).

This 19th-century cross of Saxon design marks what is traditionally thought to have been the site of St Augustine's landing on the shores of England in AD 597. Accompanied by 30 followers, Augustine is said to have held a mass here before moving on.

St Augustine’s Cross stands close to the site at which an important meeting between St Augustine and King Ethelbert is said to have taken place nearly 1,500 years ago.

Remains of a grammar school for church choristers, founded in the mid-15th century by Ralph, Lord Cromwell, the builder of nearby Tattershall Castle (National Trust).

Tattershall College was built in 1460, four years after the death of its patron, Lord Cromwell, and was completed by William of Wainfleet, Bishop of Winchester.

This building formed part of the complex of college buildings in Tattershall village and is thought to have been the grammar school.
