The Pergamon Museum features large scale rebuilds of archeological structures such as the Pergamon Alter, Ishtar Gate, and the Market Gate of Miletus. The entire museum is easy to digest, and can be walked in just a few hours. Also, I know the first photo isn't of the museum, but it's next to it. Close enough? Regardless, I highly recommend ordering tickets online, as it allows you to bypass a crazy long line that could be hours long.
