Although the focus of the MENAI HERITAGE EXPERIENCE is the amazing historical engineering feats of the construction of Thomas Telford's Suspension Bridge and Robert Stephenson's Britannia Bridge across the Menai Strait as exhibited in the famous BRIDGES EXHIBITION it has now a lot more to offer. Fabulous films, artefacts and drawings. Local history, and qualified guided tours of the historic waterfront and the bridges.
K' NEX bridge building, drawing and colouring and quizzes for children.

Around each site where a pier was to stand, a coffer dam, a sort of watertight caisson, was built. The dam was sealed with clay and the water pumped out. Most coffer dams were built of logs weighted down with stones. They took longer to put in place than did floating dams, but could be left over the winter and were easier to seal. The floating coffer dam, for its part, could be towed away after use, but its success was marred by the difficulty of keeping the water out of the work chamber.

The Calcutta Pit was one of 5 collieries (pits) in Swannington. These gradually stopped being mined in the late 19th century. However, when pumping stopped in these pits, the water began to seep down into mines in the newly developing town of Coalville. In order to solve this problem, it was necessary to set up a Joint Pumping Company, at the former Calcutta mine to drain the whole new coalfield. The Calcutta pumping engine was made by Robert Stephenson and Co. It was capable of removing 54,000 gallons of water an hour. It was installed in 1877 at a cost of £13,000 and worked until 1947.

2010 will be the 175th anniversary of the first steam locomotive trip in Germany. The cities of Nuremberg and Fürth won the race for the construction of the first railway line in Germany.


The Adler (German for "Eagle") was a Robert Stephenson and Co. locomotive built to order in 1835 and delivered to the Bavarian Ludwigsbahn to travel between the two cities.

Born in 1814: After acting as mathematical master at Brook Green, andthen as a surveyor in the west of England, went to London in 1846 and met Robert Stephenson, who appointed him superintending engineer of the Menai Strait Bridge, which was opened on 5 March 1850. In that year he published The Britannia and Conway Tubular Bridges (3 vols). In August 1850 he became engineer to the Electric and International Telegraph Company, and took out the first of several patents for ‘electric telegraphs and apparatus connected therewith’. From then on he divided his time between electric and hydraulic engineering. Clark's Two Mile Telegraph used on LNWR between London and Rugby from 1855. On 4 February 1856 he took out a patent for ‘suspending insulated electric telegraph wires’, but most of his patents were for improvements in dry docks and floating docks, in the methods of lifting ships out of the water for repairs, and for constructing piers.


Clark eventually became an experienced hydraulic engineer with the firm of Clark, Stansfield & Clark, consulting engineers of Westminster, when he was called upon in 1870 by Edward Leader Williams to design a boat lift to raise boats 50 feet from the River Weaver to the Trent and Mersey Canal. Clark designed the original hydraulic structure opened in 1875, which was later replaced by a wire rope and pulley system from 1908 to 1983 before being returned to hydraulic operation in 2002.


He was elected a member of the Institution of Civil Engineers on 3 December 1850, and contributed many papers to their Proceedings, being awarded a Telford medal in 1866 for his paper ‘On the hydraulic lift graving dock’, and a Watt medal in 1868 for those on ‘The durability of materials’. Two years' residence in Buenos Aires, Paraguay, and Uruguay, provided material for his Visit to South America (1878). Edwin Clark died at his home, Cromwell House, Marlow, on 22 October 1894.
