of the national treasures, who remained loyal to the London-based Polish government-in-exile, was reluctant to return them to Poland, which had fallen under communist rule and Soviet influence. After lengthy negotiations, the first batch of the most important objects, including Szczerbiec, was ultimately returned in 1959; the rest followed in 1961. Since then, the Polish coronation sword has been on permanent display in the treasure vault of the Wawel Castle. Historical replicas A treasury inventory of the Radziwiłł family's Nieśwież Castle (now Nesvizh in Belarus) made in 1740 includes a detailed description of a sword decorated with symbols of the Evangelists and inscriptions identical to those on Szczerbiec. According to the inventory, it was a gift from Crown Prince Jakub Sobieski to Prince Michał Radziwiłł, but the original source of the supposed replica was not given. An inventory made in 1738 of the treasure vault of the Sobieski family's Żółkiew Castle (now Zhovkva in Ukraine) mentions "an estoc (koncerz) covered with golden plates bearing images of the Four Evangelists; Skanderbek's." Based on this record, historian Aleksander Czołowski hypothesized that a replica of Szczerbiec was forged as early as 1457 and awarded to George Kastrioti Skanderbeg, the national leader of Albania, in recognition of his victory over the Ottoman forces (see Battle of Ujëbardha). After King John III Sobieski defeated the Ottomans in the Battle of Vienna in 1683, Albanians presumably returned the sword to him. His son, Jakub, possibly passed it on to Michał Radziwiłł as a present. There are doubts, however, whether the swords known to have been at Żółkiew in 1738 and at Nieśwież two years later, were in fact the same sword. The Radziwiłłs' castle was plundered by the Russian army in 1812 and the subsequent fate of their replica of Szczerbiec is unknown. This fact cast doubts over the authenticity of Szczerbiec held in the Hermitage. Some experts suspected that the sword possessed by the Russian imperial museum was in fact the Nieśwież replica, not part of the original royal insignia. Another historically notable replica of Szczerbiec was produced probably in Dresden, Saxony, at the time when the original was in Prussian hands. It is modest and inexact; the handle is carved in bovine bone and the niello is imitated with black paint. Designs on the handle are patterned on those of the genuine Szczerbiec, except that the crosses and letters on the pommel were replaced
