The arcade is a unique structure in the street that survived the war.
No restoration in the last 80 years.
The arcade wall is a rare relic of pre-war Warsaw.
The arcade should remain as a kind of „witness for history” incorporated in modern surroundings.
Guidelines for restoration
• Improvement of aesthetics
• Creation of an interesting background for owner’s needs (exhibitions, workshops, other activities)
• Creation of an attractive point within the street
• Conception of guidelines for further architectural arrangements
Owner’s expectations
• Strict protection of historic substance and values. • Petrification of the wall in its current shape with some limited
interventions. • Elimination of current risks (e.g. new gutters, anti-graffiti layers)
Authorities’ recommendations
Present status:
• Preliminary research -
• Survey and initial analysis -
• Design of conservation -
