The Union of Lublin, established in 1569, tied together the Kingdom of Poland and the Grand Duchy of Lithuania, creating the so-called Commonwealth of Both Nations, characterized by a single monarch, a common parliament and one currency.

It is commemorated by the three historic monuments located in Lublin which are parts of the site.

The Union was an exceptional case of the democratic integration of two countries with peaceful and inclusive coexistence of people from various ethnic and religious backgrounds.
