There are two ways to visit the interior of the German Parliament Building. The ordinary way is to visit the glass dome. The visit time is relatively free and there is no time limit. The other is to enter the National Conference Hall to participate in a 40-minute lecture. The lecture is not held many times, and there are not appointments every day. Only use the whole English explanation, very good experience, after the lecture can continue to visit the glass dome freely, no need to make an appointment, if the time can be arranged, be sure to make an appointment on the official website as soon as possible.
