The Pontcysyllte Aqueduct is a navigable aqueduct that carries the Llangollen Canal across the River Dee in the Vale of Llangollen in northeast Wales.

The aqueduct was designed by civil engineers Thomas Telford and William Jessop. The work, which took around ten years from design to construction, cost around of £47,000. Adjusted for inflation this is equivalent to no more than £4,060,000 in 2021.

The length of canal from Rhoswiel, Shropshire, to the Horseshoe Falls, including the main Pontcysyllte Aqueduct structure as well as the older Chirk Aqueduct, were visited by assessors from UNESCO during October 2008, to analyse and confirm the site management and authenticity. The aqueduct was inscribed by UNESCO on the World Heritage List on 27 June 2009.

The canal here is poetically titled 'the stream in the sky'. Walking across the aqueduct can cause severe vertigo, and many people start out then turn back, which isn't surprising as the structure is 126 ft (38 m) high, with a narrow footpath.

The PiP is a sculpture representing 'the stream in the sky'.
