Why is the White House a significant monuments ?

The white House in Washington DC is a monument steeped in history. It was George Washington, the first President of the US, who chose the site for the White House.
The cornerstone was laid in 1792, and a design submitted by Irish-born architect James Hoban was chosen. After eight years of construction, President John Adams moved into the White House in 1800, and it has been the home of American presidents since then.

The beautiful white building has 132 rooms, and 35 bathrooms in, and it the only  building in the world that is simultaneously the home of a head of state, the executive office of a head of state, and is regularly open to the public for tours.
