This Victorian Bridge is now more than 100 years old. Designed by Wolfe Barry and Horace Jones, and completed in 1894, the middle of the bridge can be raised to permit large vessels to pass the Tower Bridge. It used to be raised about 50 times a day, but nowadays it is only raised 4 to 5 times a week. The bridge is 60 meters (197 feet) long and its towers can rise to a height of 43 meters. From the top of the towers, you have a great view on the center of London. You can also visit the inside of the tower, where you can observe the original mechanism used to raise the bridge.
