When Solomon Wayne saw the Pinkney's sketches he knew he had found the style for a new kind of building, unfortunately the tallest fo the buildings, the tower, was unfeasable at the time. Later, as new building materials and technologies (tying a building's foundation into the bedrock) were developed, it became possible to make that vision a reality.
Solomon's son, Alan Wayne, working with other important members of Gotham elite pushed for the construction of a tower that would stand as inspiration to the good people of Gotham. It was constructed in 1888 looking much like Pinkney's original drawing of it. Many other "Gotham style" skyscapers followed.
Over a 1,000 feet tall, the tower would be the tallest in Gotham. Built as a symbol to welcome all of those who enter Gotham City. For each entry point into the city, there was built a gargoyle or 'guardian,' to welcome visitors. The tower was also tied into the railways lines around it. At the top of the tower is an observation deck covered by a giant glass dome. It is currently the home of Wayne Enterprises.
