Italian Renaissance building for German members of parliament was designed by Frankfurt architect Paul Wallot. The first stone was laid in 1884 by Kaiser Wilhelm I. Works have been carried on for ten years. Reichstag was severely damaged during street fights in 1945. Its walls still carry inscriptions of victors.
In 1954, in order to avoid collapse of the dome, it had to be blown up. The new dome was built by Englishman Norman Foster. You can visit Reichstag by booking a ticket at its website. It is also possible to do it on the spot, but then be ready to spend some time on it. It is better to climb to the dome accompanied by an audio guide. Excursions are available in German, French, English, Spanish, Italian, Dutch, Polish, Russian and Turkish languages. There are versions for children and people with limited abilities. Nice views on Berlin open from the top.
