Lublin is the largest city in southeastern Poland. It is home to a long and fascinating history and stunning Polish architecture. It was here where the Lublin Union was signed in 1569 - a pact that sealed the constitutional union between the Kingdom of Poland and the Grand Duchy of Lithuania creating a free republic associated with a single Parliament, an elected king, a currency and, ethnic and religious tolerance. Monuments in Lublin stand out as physical reminders of an important milestone in the development of the principles of European democracy, four centuries before the EU was created. During the walk through the beautiful old town we will see many interesting monuments, among them the 14th century Krakow Gate, Market Square, town hall and castle. One cannot leave Lublin without having seen the Dominican Church and the Cathedral of Saints John the Baptist and John the Evangelist.
