Royal Border Bridge — Castle Vale Park Viewpoint

Castle Vale Park drops in terraces and steps from Berwick-upon-Tweed station toward the River Tweed, on the east side of the railway. The standing point, on the park's upper path about 67 m (220 ft) from the north end of the Royal Border Bridge, looks south-west along the viaduct as it crosses the river toward Tweedmouth: a raking view of the arches receding one behind another, rather than a side-on profile. Trains are close to the station here, so northbound services are slowing for the Berwick stop or running through, and southbound ones are just getting away. A long flight of steps continues down to the riverside path along the north bank, which passes below the arches for a closer, looking-up view. The viaduct carries only the railway; there is no public way across it.

The park occupies part of the old Berwick Castle grounds, on the bank between the station and the tidal River Tweed, with rose gardens, pergolas and seating. The viaduct is 659 m (2,162 ft) long and stands 37 m (121 ft) above the river, its 28 arches of 60 ft (18 m) each striding across the water to Tweedmouth on the south bank. The town walls and the Royal Tweed road bridge are close by downstream.

Robert Stephenson designed the bridge, with Thomas Elliot Harrison doing most of the planning and George Barclay Bruce as resident engineer. It was built between 1847 and 1850 to close the last gap in the railway between London and Edinburgh along the east coast, and opened on August 29, 1850, when Queen Victoria, accompanied by Prince Albert, named it the Royal Border Bridge. It took some 8 million cubic feet (227,000 m3) of stone and 2.5 million bricks, is 659 m (2,162 ft) long with 28 arches, and is Grade I listed. Castle Vale Park below it was given to the town by the Berwick baker John Cairns in 1928, restored with Heritage Lottery funding and reopened by the Duchess of Northumberland in 2014, when a viewing platform was added (fabulousnorth.com). A 1930s railway advertising poster showed a train entering Berwick over the bridge as seen from the park.

The bridge is one of the great set pieces of the East Coast Main Line and Castle Vale Park featured on a classic 1930s railway poster of a train entering Berwick over it. Despite its name, the bridge does not cross the border: Scotland begins a few kilometres further north. The park and the riverside path below give two very different angles within a couple of minutes' walk.
