There are few places as important to American business as the New York Stock Exchange.

The exchange is celebrating its 225th anniversary this week, and a multimillion-dollar renovation completed in February pays homage to its past in every conference room. Walking around the exchange's many rooms above the trading floor, you'll see historical artifacts like a signed letter from Thomas Edison, a gift from Czar Nicholas II of Russia, and a signed guitar from Jimmy Page.

We recently took a tour of the stock exchange floor and its newly renovated rooms to see what a typical day is like inside the New York Stock Exchange.
