The “Grodzka Gate – NN Theatre” Centre is a local government cultural institution based in Lublin. It works towards the preservation of cultural heritage and education. Its function is tied to the symbolic and historical meaning of the Centre’s location in the Grodzka Gate, which used to divide Lublin into its respective Christian and Jewish quarters, as well as to Lublin as a meeting place of cultures, traditions and religions.

Part of the Centre are the House of Words and the Lublin Underground Trail.

About the databases

The system, consisting of four basic modules: People, Places, Events and Sources that interconnect and complement each other, allows processing, organizing and the presentation of a large amount of data about the city and region, in a simple and transparent way.


Every person and place (address marker) is treated as a separate item and as such has its own page and identifier, being at the same time part of a larger network of information. The same applies to source quotations and events. All these elements are then used for more complex narratives, such as family or organization descriptions, thematic maps or event calendars.


The historical spatial information system (H-GIS) is an integral part of the databases, which precisely maps, describes and helps to understand the spatial transformations that have occurred in a given area. The location of old streets and plots can be identified on a modern map or by satellite view. Thanks to available calibrated layers of historical maps, it is possible to quickly identify the former street name or address in case it was changed.


The goal of the creators of this system is to bring about a situation in which all references to Lublin residents and addresses, from all eras for which resources are available (since the 14th century on) will be recorded and described in the databases. This ambitious goal requires many years of interdisciplinary work on acquiring, developing and sharing information from multilingual sources (available in Latin, Polish, Russian, German, Hebrew and Yiddish). Currently, the majority of material used originates from records based on sources from the interwar period and the German occupation period, mainly concerning Jewish residents of the city. This is the result of the project "Lublin. 43 thousand” which documents the exterminated Jewish community of Lublin. In the meantime, a map of places and a database of 19th-century Lublin residents is being developed and sources from even earlier historical periods are being processed.


The database system was invented and developed primarily for Lublin and its residents. However, the resources placed here go beyond the territorial framework of our city. Mention is made here of both, the Lublin region and places located outside of our region and country, which appear in projects and activities implemented by the Center (e.g. "Lublin-Antwerp").


To date, over 72,000 records have been entered into the Person database, over 12,000 records into the Places database, approximately 127,000 records into the Events database, and 67,000 references into the Sources database. These numbers are constantly changing.
