Lizards in wrought iron in the Vigeland Museum's Monolith room.
Vigeland is least famous for his wrought iron production. The most complicated of these works were the wrought iron gates in the Vigeland Park, but he also designed smaller wrought iron pieces, including lamps and candlesticks for his apartment.
Vigeland made working drawings which he then delivered to different blacksmiths who worked for him. He often took his drawings to Karl Bilgrei's forge, where Alfred Mikkelsen worked as his apprentice. In 1928 Vigeland built his own forge at Frogner, due to the amount of work to be done on the park’s gates. He hired Mikkelsen and two other blacksmiths to work for him, and this resulted in a close collaboration.
