[1] NN Theater was established in 1990 in Lublin Drama Group, accommodated at that time in the Grodzka Gate and adjoining buildings.

[2] In 1998 the theater became a detached, independent organization and received its current name Ośrodek "Brama Grodzka — Teatr NN".

As Tomasz Pietrasiewicz explains, literary adaptation of Herman Melville novel "Moby-Dick" played on the stage in June 1995 became a farewell to the certain period of producer's theater life.

Building of the center has hosted many expositions, though its structure, characterized by a range of narrow corridors, some dead-end ones, is far from being an idyllic place for a "typical" exhibition.

In addition, there is a room dedicated to the Holocaust victims with seventy coloured photos of Lublin ghetto, taken by a German soldier Max Kirnberger.

Another eye-catching item of the exposition are models of the old part of the city in 1930s – one actual and one multimedia one with replicas of 840 buildings, such as town houses, shops, synagogues etc.

Nowadays a bus station and lanes occupy its place, whereas the main street of the Jewish district – Szeroka – gave way to an asphalted parking lot.

At the site of the whole former Lublin Ghetto lights go down, creating a striking contrast with other parts of the city humming with life and pitch black territory around the castle.

These are recorded audio materials of the stories told by the inmates of Lublin castle prison and local inhabitants, who witnessed the times of ghetto functioning and liquidation.

Getting closer to Tysiąclecia Ave., even bus station loud-speakers start to ring with voices, but having reached the synagogue, participants see that their way is blocked with a heavy black curtain.

An original street lantern on Podwale St. that has remained there since the prewar times (now adapted for electricity) embodies Jewish presence in the area.

[10] Mystery of memory «Jedna Ziemia — Dwie Świątynie» (English: "One Land - Two Temples") was organized within the framework of the Congress of Christian Culture, held in Lublin on September 15–17, 2000.

In the passage of Grodzka Gate, a symbolic place of unity of Christian and Judaic cultures, the soil from two pots was blended in one large barrel by a Polish and a Jewish child and professor of John Paul II Catholic University of Lublin, Romuald Jakub Weksler-Waszkinel.

The Center collected a sizable piece of data about Henio (including the letters and pictures sent by his family to the relatives), that enabled it to create a rather in-depth reconstruction of boy's life.

Pursuant to oral history guidelines, the "Grodzka Gate" collected memories of almost 2,000 people and recordings of more than 3,000 hours of audio and video materials.

[15] Lublin Underground Route (Polish: Lubelska Trasa Podziemna) is one of the separate departments of the "Grodzka Gate", opened for visitors in 2006.

[17] Museum of printing House of Words (Polish: Dom Słów) on Żmigród, 1 is another separate department of "The Grodzka Gate".

House of Words unveils for its visitors all major stages of the book creation process – pagination, printing of pictures, typography etc.
