The nearest Underground station to Big Ben is Westminster, which lies on the Jubilee, Circle and District lines. This iconic building is within the congestion charging zone, so arriving by car is inadvisable, unless you opt for a classic black cab. There are several London bus routes running past the tower, which is also served by several river buses.
The tower is open Monday to Friday 9.15am until 10.15, and then 11.15am until 2.15pm.
You can book an official tour of the Elizabeth Tower for free on both weekdays and Saturdays. Hour-long talks offer you an insight into the history and cultural significance of the capital city's timekeeper. Tickets can be purchased online, by phone or in person from the Ticket Office.
