Construction of the Alexandra Bridge, named after the Princess of Wales, over the River Chenab, commenced in November 1871. It was completed when the Prince of Wales hammered in the last rivet during his visit. The steel hammer, which the Prince used, was presented in this steel and gold casket of exquisite workmanship. Both are decorated using a technique called kuftkari¸ which involves hammering gold wires onto a hatched surface. At the time of the bridge's completion, it was one of the longest bridges in the world, spanning more than 3000 metres.
