Readers who suffer from vertigo should perhaps look away now. The world\u2019s highest canal aqueduct measures just 12 feet across \u2013 including the towpath \u2013 and carries narrowboats and pedestrians a full 126 feet above the River Dee in north-east Wales.<\/strong><\/p>

What is the Pontcysyllte Aqueduct?<\/h2>

It was originally designed to carry the Llangollen Canal<\/a> across the River Dee by building a conventional series of locks that would bring the canal down into the Vale of Llangollen then back up the other side, crossing the Dee via an embankment. <\/p>

However, the civil engineering team of\u00a0Thomas Telford<\/a>\u00a0and\u00a0William Jessop<\/a>\u00a0proposed something far more ambitious: a cast iron trough borne across the vale for 336 yards supported by 18 stone arches.<\/p>

A decade in the making, Britain it was opened in 1805. It had cost nearly \u00a350,000 \u2013 close to \u00a35m in today\u2019s money \u2013 but Telford and Jessop\u2019s confidence would prove well founded.<\/p>

Oddly, given the time-consuming and expensive nature of this piece of infrastructure, the waterway it was intended to serve was never finished. The Ellesmere Canal would have linked the River Severn with Liverpool, but financial difficulties meant that long stretches were never dug. In fact, the aqueduct was the last section of any great moment to be completed.<\/p>

How high is Pontcysyllte Aqueduct?<\/h2>

The Pontcysyllte Aqueduct stands at an impressive height of\u00a0126 feet (38.4 meters)\u00a0above the River Dee.<\/p>

The aqueduct spans a length of\u00a01,007 feet (307 meters), making it the longest aqueduct in Great Britain.<\/p>

When was Pontcysyllte Aqueduct built?<\/h2>

Construction of the Pontcysyllte Aqueduct began in\u00a01795\u00a0and was completed in\u00a01805. It took ten years to design and build this engineering masterpiece.<\/p>

Where is Pontcysyllte Aqueduct?<\/h2>

The Pontcysyllte Aqueduct is near the village of Cefn Mawr, not far from Llangollen in the\u00a0Vale of Llangollen in northeast Wales.\u00a0<\/p>

When was the Pontcysyllte Aqueduct granted UNESCO World Heritage status?<\/h2>

Granted in 2009, this World Heritage Site<\/a> includes not just the aqueduct, but also the canal and associated engineering features, covering 11 miles (18 km) of scenic canal route.<\/p>
