著名景区英文介绍美国国会大厦(3)

House, as well as the Supreme Court, ready for use by 1819. Bulfinch redesigned the central section, making the dome that topped the section higher. Bulfinch spent his last couple of years on the Capitol's landscaping and decoration until his position was terminated in 1829.

By 1850, the Capitol could no longer accommodate the increasing numbers of senators and representatives. Another competition was held offering $500 for the best plan to extend the Capitol. Unable to decide between the plans, Congress divided the money between five architects and Thomas U. Walter was chosen to complete the task. Walter supervised the construction of the extensions, making sure they were compatible with the existing style of the building, but using marble for the exterior instead of sandstone, which deteriorates quickly. As the wings progressed, they more than doubled the length of the Capitol making the dome too small for the new proportions. In 1856, the old dome was removed and work began on a replacement with a new, fireproof cast-iron dome. Construction was suspended in 1861 so that the Capitol could be used as a military barracks, hospital and bakery for the Civil War. However, in 1862, construction resumed, because Lincoln believed that the Capitol must go on, just as the Union must go on.
