The British Museum in the Bloomsbury section of London was established in 1753, largely based on the collections of the Irish physician and scientist Sir Hans Sloane. It first opened to the public in 1759, in Montagu House, on the site of the current building. Its expansion over the following 250 years was largely a result of expanding British colonisation and has resulted in the creation of several branch institutions, the first being the Natural History Museum in 1881
Its ownership of some of its most famous objects originating in other countries is disputed and remains the subject of international controversy, most notably in the case of the Elgin Marbles of Greece and the Rosetta Stone of Egypt.
Coming from America with its relatively short history it was amazing to see these artifacts you only read about in books before. The museum has an extensive Egyptian collection.
