Monuments to visit Denbighshire (Sir Ddinbych)

Pontcysyllte Aqueduct is a monumental aqueduct, almost 40 meters high and 300 meters long, spanning the torrential River Dee and carrying the Llangollen Canal in a long cast-iron tank, supported by bold yet lightweight pillars. This innovation has enabled the company to expand its transport capacity. In the past, horse-drawn boats crossed this suspended waterway, carrying coal, lime and iron from the mines and quarries of the Llangollen valley to Ellesmere. Crossing it today is truly impressive!

A pioneering masterpiece of engineering andmonumental architecture. Completed in the early ^19th century, this aerial canal-bridge was built by the famous Scottish engineer Thomas Telford (1757-1834), and is popularly known as "the canal in the sky" by locals. A pioneering work in terms of its technological choices and architectural boldness, it has been a UNESCO World Heritage Site since June 2009. It bears witness to the unique production capabilities of the British steel industry at the time.

This magnificent structure features a cast-iron and wrought-iron shell, set as if by magic on tall, slender pillars of elegant architecture. The Pontcysyllte canal bridge(Traphont Ddŵr Pontcysyllte in Welsh) represents a civil engineering feat of the Industrial Revolution. Its construction in a single reach, without any locks, despite a difficult geographical environment, makes it a remarkable example of artificial waterway construction, which has inspired many other projects around the world.

Today, its vocation is essentially tourism. The bridge-canal is now equipped for river tourism and is a tourist destination in its own right. Its canal, filled almost to the brim with water, can be crossed by boat (via Llangollen Wharf), while its narrow, bolted, cantilevered sidewalk allows passage on foot or by bike. Either way, it's a vertiginous experience!

What's more, the Trevor Basin Visitor Centre is right beside the aqueduct. It houses a collection of historical artifacts dating back to the construction of the Pontcysyllte Canal Bridge. Visitors can also enjoy a video recounting the history of this impressive structure, as well as a children's activity area and gift store.

Built at the request of Edward ^I in 1282 by Henry de Lacy, one of his chief commanders during his conquest of Wales. It was built in two parts, the second of which began in 1294. Today, the grandiose ruins of a ^13th-century fortified castle remain, including three connecting towers (similar to those of Caernafon Castle), atop a hill near Denbigh. We particularly recommend the 1 km walk along the ramparts, dating from 1282: the architecture is impressive and the views fabulous.

The "Fortress of the Crows" is a ruined prehistoric fort, perched at 266 meters. There is not much to see from the castle but the view is superb and the place is full of legends. According to these legends, the fortress was built by one of Queen Corwena's twin sons, Bran, after his brother Beli moved to London, and the Queen to another city. Legend has it that the name Bran was actually a code name of the Princes of Arthur for the Holy Grail. The Holy Grail would be, therefore, buried in the foundations of Dinas Bran!

Very pleasant visit in a very different castle. We are here in a beautiful house built in 1300, on the model of Beaumaris, but whose interior dates mainly from the 18th century (rich furniture, majestic staircase, Mortlake tapestries ...). The building is still partly inhabited by the Myddelton family since 1595, when their ancestor bought the castle for £5,000.

Don't miss the superb park, a small jewel of English gardens, laid out at the end of the 18th century by a great British landscape architect Lancelot "Capability" Brown.
