The Fanta wing of Prague's main railway station will once again be adorned with a sculpture of golden wings from 1907. The statue, which is part of the winged wheel sculpture, has been under construction for about a year. Repairs to the roof and facade of the building are underway as well as to the interior of the Art Nouveau building. The reconstruction of the facade and roof, the total cost of which is estaimated at CZK 220 million should be completed this June. Restorers re-gilded the golden wings before placing them on the historic building using 4,875 leaves of 24-carat gold. Reconstruction was necessary as the sculpture was threatening to fall from the building due to the corroded steel structure of the golden wings. The Railway Administration also plans to repair the interior of the Fanta building by 2023, which, together with the adjacent hall above the platform, forms the largest Art Nouveau monument in the Czech Republic.
