Tip:
It's especially nice to experience the nightfall, with the lights of the city, at the London Eye. To do this you should start the ride shortly after sunset . Usually the queue times are not too long in the evening hours. The ride duration is around 30 minutes.

Usually you can have a look at the outside of the palace every day, a visit of the royal premises is only possible during summer and autumn on certain days

All fans of the royals, who would like to have a tour through some of the magnificent rooms inside, should schedule their London Trip for summer time and book their tickets online and on time.

At any time, you can visit the Big Ben clock tower and the building of the Houses of Parliament from the outside. The Houses of Parliament is open for tours almost every Saturday and on several weekdays during parliamentary holidays. 

If you are looking for a good photo spot for the Big Ben, you should check the view from the nearby Westminster Bridge. This is also a good location to listen to the famous bell sounds at every full hour.
