we highly recommend going to see one of the spectacular Changing of the Guard ceremonies. The changing of the guard takes place in front of Buckingham Palace, in front of the Horse Guards Palace and at St. James Palace. The most spectacular one is undoubtedly the one which takes place in front of Buckingham Palace. The new Guard, normally belonging to one of the Foot Guard’s (infantry) five regiments, with its scarlet uniforms and tall bearskin hats, line up in the Wellington Barracks courtyard in Birdcage Walk, at 10:45 a.m., to then march to the palace for the changing of the guards at 11.27 a.m.
from May to the beginning of August the changing of the guard takes place at 11.30 a.m.;
from August to April it takes place on alternate days;
the changing of the guard does not take place when it rains.
