This looks like another (lost-in-translation?) chapter in the sputtering attempt to repatriate the Altar ... from Turkish Daily News:

The Bergama Zeus Altar, one of the most important pieces among Anatolian historical treasures, lures crowds at the Pergamon Museum in Berlin, thousands of kilometers away from its motherland, reported the Anatolia news agency.

Pergamon is one of the five museums on the Berlin Museum Island (Museumsinsel), visited by almost all tourists in Berlin. It exhibits archaeological works, which were found during the archaeological excavations initiated in 1865 by Carl Humman. The Bergama Zeus Altar (165 B.C.), regarded as the most precious piece among the archaeological works that are exhibited in the museum, receives great interest from domestic and foreign tourists in Berlin. It is reported that the visitors of the Pergamon Museum pay 30 million euros in a year for the entrance fee and gift products that are sold in the museum.

The museum's Islamic Arts section, where pieces from various regions including Anatolia are on display, also draws attention of visitors. It is reported that Humman came to the region in 1864 for a road construction project and showed great interest in the works found by chance during the construction. Bergama (Ancient Pergamon), one of the oldest settlements in the history of civilization, came to light during the excavations started after 1864.

The Zeus Altar, which was constructed by the Pergamon King Eumenes II (197-159 B.C.) as a memorial of his victory against the Galatians, was taken to Berlin nearly 130 years ago. What is interesting is that the tomb of Carl Humman, who took the Zeus Altar to Germany, is in the Acropol in Bergama by his will.
