Besides the pyramids? Some of the early, especially Romanesque cathedrals were built that way. Even the National Cathedral in Washington DC was built over a long period of time and involved many people. The gargoyle carvers came from Italy. The longest-running construction project in Washington, D.C., history officially began on September 29, 1907, when workmen laid the Cathedral’s foundation stone. President Theodore Roosevelt and the Bishop of London spoke to a crowd of ten thousand. The stone itself came from a field near Bethlehem and was set into a larger piece of American granite. On it was the inscription: “The Word was made flesh, and dwelt among us” (John 1:14). 1990 – The completion of the west towers marked the end of 83 years of construction.
