North Berwick Law watch-house

North Berwick Law, also known simply as Berwick Law, is a conical hill which rises incongruously from the surrounding landscape (indeed, this is the definition of the Lowland Scots word "law"). It overlooks the East Lothian town of North Berwick and stands at 613 ft (187 m) above sea level.

The summit bears remnants of an Iron Age hill fort, and the ruins of later military buildings that were once used by lookouts in both the Napoleonic Wars, and in World War II.

Tantallon Castle is a semi-ruined mid-14th-century fortress, located 5 kilometres (3.1 mi) east of North Berwick, in East Lothian, Scotland. It sits atop a promontory opposite the Bass Rock, looking out onto the Firth of Forth. The last medieval curtain wall castle to be constructed in Scotland, Tantallon comprises a single wall blocking off the headland, with the other three sides naturally protected by sea cliffs.

Tantallon was built in the mid 14th century by William Douglas, 1st Earl of Douglas. It was passed to his illegitimate son, George Douglas, later created Earl of Angus, and despite several sieges, it remained the property of his descendants for much of its history. It was besieged by King James IV in 1491, and again by his successor James V in 1528, when extensive damage was done. Tantallon saw action in the First Bishops' War in 1639, and again during Oliver Cromwell's invasion of Scotland in 1651, when it was once more severely damaged. It was sold by the Marquis of Douglas in 1699 to Hew Dalrymple, Lord North Berwick and the ruin is today in the care of Historic Scotland.
