 The Marine Barracks building also dates from this period, as do several other buildings including Georgetown's hospital, which continues to fulfil the purpose for which it was built.The site of the old settlement, closer to the sea, was then used for storage and maintenance (the surviving Main Storehouse of 1848 was once claimed to be the largest building in the southern hemisphere).Before long, to meet the demands of an increasingly steam-powered navy, coaling facilities were built, and in 1862 a 'steam factory' housing metalworkers, a machine shop and smelting works, was established.
