I visited Berlin for the first time in my life last weekend; I loved it!

My favourite thing about it was how the remaining parts of the Berlin Wall are an integral part of the city, left standing and unprotected in the middle of the city.

Some bits still look like what I imagine the Berlin Wall looked like back in 1989: grey and sad. Some bits bear the marks of more modern times, written and graffiti'ed on in the last few years. Finally, a 1.3km-long part of the wall was turned into an "international memorial for freedom" in 1990, when 105 paintings were painted on the east side of the Wall by artists from all over the world. It's now called the East Side Gallery.

Apart from the East Side Gallery, I enjoyed visting Deutsches Historisches Museum and the Museum für Fotografie. I especially enjoyed an exhibition called Japanese Photography from the Meiji Period, which showcased amazing photographs from as early as the 1860s.
Although we couldn't get in and actually visit it, I also liked the Reichstag building.
