The Old Lwowska Gate was originally built as a makeshift one with an earthen curtain wall after 1591. After 1599 a masonry

gate was built in accordance with Bernardo Morando’s design. The gate remained in its original form till the 1820 when it was walled up and turned into a prison after the New Lwowska Gate was built. The foreground of the gate was provided with a ravelin, additionally protected by a huge redan at the time of the Duchy of Warsaw. There might have been only a berm designed by Jan Michał Link at the end of the 17th century at the site. In 1820 Captain Jan Paweł Lelewel built the New Lwowska Gate on the axis of the curtain wall. At the same time a caponier was built in the line of Carnot wall in the moat under the bridge. After fortress liquidation, the curtain wall was destroyed and a road leading to the town was built between the two gates. In 1937 attempts were be made to rebuild the Old Lwowska Gate; the works supervised by Jan Zachwatowicz were disrupted by the war. Masonry fragments were finally completed in 1979. In 1980 the New Lwowska Gate started to house the K. Namysłowski Orchestra. The curtain wall between the two gates has not been restored so far.
