The Regent's Canal was built to link the Grand Junction Canal's Paddington Arm, which opened in 1801, with the Thames at Limehouse. One of the directors of the canal company was the famous architect John Nash. Nash was friendly with the Prince Regent, later King George IV, who allowed the use of his name for the project. The Regent's Canal Act was passed in 1812 and the company was formed to build and operate it. Nash's assistant, James Morgan, was appointed as the canal's Engineer. It was opened in two stages, from Paddington to Camden in 1816, and the rest of the canal in 1820.
