The National Maritime Museum (also known as the Royal Observatory, Greenwich) is a museum dedicated to the sea, ships, astronomy and time. It houses over two million objects and is well known as being the leading maritime museum in the UK. It also has the worlds largest historical reference library, containing more than 100,000 books, some dating as far back as the fifteenth century.

It was formally opened in 1937 by King George VI. These days, however, it has more luxuries with the Regatta Café that serves hot meals as well as snacks and hot and cool drinks for the majority of the day. The museum itself is open from 10am to 5pm and in the Summer months, it stays open until 6pm. It is free to enter the sit, although the Royal Observatory and the Caird Library do charge a small entrance fee.

You can get to this museum though the normal routes - bus, train and underground but you can also get here by the river cruiser or river buses that travel along the Thames.
