British Museum
The Museums collection continued to get bigger over the following years, and more and more buildings were added to hold the new objects. Important discoveries by people working for the British Museum included the Mausoleum of Halicarnassus by Charles Newton in 1857 and the Temple of Artemis in 1869. Many things found at these sites were taken to the Museum, where they have remained ever since. In 1852 the British Museum's famous round Reading Room was opened. It had enough space to display a million books at once.
