Constructed in 1957 as the “Center at the Zoo,” the building represented an architectural revolution and was a symbol for new lightness in the post-war period. Berlin residents called it the “Bikini House.” The recent restoration unites the past and present in an unconventional manner: This landmark building now houses flagship and pop-up stores, restaurants, the Zoo Palast movie theater, and the hotel 25hours. Highlights include the roof terrace the size of a soccer field and views of the zoo.
