In the early 19th century, Scottish civil engineer Thomas Telford (1757-1834) built the A5 road as the main London-to-Dublin mail route. The current ‘Pont Pen-y-benglog’ bridge over the Afon Ogwen was built to replace a difficult, steep section of the earlier coach route at the western end of Llyn Ogwen. The surviving arch of the earlier, medieval pack-horse bridge can be seen below the present one.
With an altitude of 950 m (3,117 ft), Helvellyn is the highest point of the eponymous mountain range lying between Thirlmere and Ullswater lakes in the Lake District. Helvellyn is the third highest mountain in England and its summit is managed by the John Muir Trust.
Aira Force is a 21-metre-high waterfall on the river Aira Beck, which flows into Ullswater. It is one of the most visited waterfalls in the Lake District and is situated within Gowbarrow Park, 300 hectares of grounds purchased in 1906 by the National Trust. The grounds were landscaped and an arboretum planted in the 18th century by the Howard family of Greystoke Castle, which is located some 7 miles to the north.
