The Point back in 1905. Pittsburgh was in the midst of an industrial boom and the Point had just been cleared for the construction of the Pennsylvania Railroad freight depot. Pittsburgh was a center for rail traffic, due to its geographic location and the ease of water transport via the three rivers. Soon the city would be inundated with rail traffic, from the B&O Railroad, the Wabash and the Pennsylvania Railroads. The one building that has always been a constant in the Golden Triangle, the Fort Pitt blockhouse, is visible, sitting slightly lower than ground level with the American flag flying from its roof.
