medal of honour at the Paris Exhibition of 1855. For the Admiralty he planned in 1845, and afterwards constructed, the packet and refuge harbour at Holyhead, and in 1847 he constructed the harbour of refuge at Portland. In the making of these great harbours he contrived, by means of elevated timber staging, to let down masses of stone vertically from railway trucks, and, by building up the masonry with unexampled rapidity to a point above sea level, contrived to reduce to comparative insignificance the force of the sea during building operations. As many as 24,000 tons (24 kt) of stone were deposited in one week. In 1850 he commenced making a new harbour at St. Peter Port, Guernsey. River improvements Rendel was much occupied in the improvement of rivers. In 1852, in conjunction with Sir William Cubitt and Richard John Griffith, he examined and reported to the treasury upon the arterial drainage works in Ireland, and in 1855 he completed the suspension bridge across the Ness at Inverness for the Commissioners of Highland Roads and Bridges. His aid was also sought by foreign countries. In 1852–53 he designed docks for Genoa; in 1853–55 he reported on the harbour of Rio de Janeiro; in 1854 he reported to the Prussian government on a naval establishment at Heppens on the river Jade; and in 1854–55, by direction of the Hamburg senate, he inspected the Elbe from Hamburg to Cuxhaven. For the Spanish, he devised a system of railways between Madrid and Oviedo, as well as improvements of the river Ebro. In England his railway work was somewhat restricted, but he executed the Birkenhead, Lancashire and Cheshire Junction Railway and in India he directed the construction of the East Indian and the Madras railways. In 1856 he reported on the new Westminster Bridge. His last work was a design for the suspension bridge across the ornamental water in St. James's Park, London. In 1852 and 1853 Rendel served as president of the Institution of Civil Engineers, which he joined in 1824. He became a fellow of the Royal Society on 23 February 1843 and was elected a member of the council. He died at 10 Kensington Palace Gardens, London, on 21 November 1856 and is buried in Kensal Green Cemetery. Legacy Rendel was a man of great energy, and implicit confidence was felt in his efficiency, tact, and honesty. His greatest enterprises were
