Architectural Models - Early staircases and domes. Over the centuries architects have made models to check details in 3D and help clients understand dimensional perspectives. In fact, Michelangelo had several models made of the St. Peter dome during the time he worked on it. These stunning architectural models were discovered in an attic and newly restored. Today these models are a main attraction at the Vatican Museum. Many renowned architects also collected architectural models for both their exquisite workmanship and their value as home décor. Our collection of early stair model and dome buildings are made of cherry and birch, finished in subtle shades of light and dark honey. The sinuous curves and arches add a fluid touch to home or corporate quarters. By Authentic Models.
