The Pergamonmuseum, located on Museumsinsel (Museum Island) on the River Spree, is one of travelers' favorite museums. Recent guests used words like "remarkable" and "jaw-dropping" to describe the museum, which was completed in 1930 and houses many works that are important to the development of ancient art and architecture. Filled with an impressive collection of Greek, Roman, East Asian and Islamic art, exhibits include pieces like the reconstructed Ishtar Gate and the Pergamon Altar – a massive monumental Greek temple that is believed to date back to 180 B.C. 

The museum is open from 10 a.m. to 6 p.m. daily, except on Thursdays when you can tour the collection until 8 p.m. The Pergamonmuseum charges 19 euros (about $21); most travelers said the price is worth the experience. You can also purchase a Berlin WelcomeCard for all of Museum Island that includes admission to each museum for up to three days, as well as free public transportation. To get here, take the S-Bahn or U-Bahn to the Friedrichstrasse stop. Before visiting, museumgoers should note that the hall containing the Pergamon Altar, the north wing and the gallery of Hellenistic art are currently under renovation and are expected to remain closed until 2023.
