A couple of weeks ago I made a day trip to Poznan from Berlin. There is a train leaving from the Ostbahnhoff station and arriving in Poznan glowny 3 hours later. Once I got there, I started to walk towards the city center, and on the way, I found a place selling pizza that had an amazing margherita—yummy!

I visited the central square, and I thought it was beautiful, surrounded by old buildings, including the Renaissance Old Town Hall. There were many ice cream places, bars, and restaurants. In the information center, they recommended visiting Ostrów Tumski, an island between the two branches of the river Warta. This island was one of the main political centres in the early Polish state, and now it's possible to visit the cathedral that houses some ruins from that era in the subterranean crypt. Very interesting city.
