Transamerica Tower, Baltimore, MD
Transamerica Tower was originally built as the "USF&G Building". This 40-story, 528-foot skyscraper, completed in 1973, in downtown Baltimore, Maryland, is tallest building in Baltimore, the tallest building in Maryland, and the tallest building between Philadelphia and Raleigh. It was one of the first skyscrapers to be constructed using a then-revolutionary method of erecting a towering central reinforced concrete column first, containing elevators and service infrastructure conduits, then followed later by the surrounding scaffolding or steel horizontal beams rising floor by floor. It is surrounded by plazas rising above a series of steps on the lower south and east sides of the block paved with pink stone panels with terraced garden plots.
