Bank in the "Irish Ghetto" near the intersection of Columbus, Carter, Franklin, and Riverbed Roads. Shipmen would find services at establishments like the "Flat Iron", the oldest Irish Bar in the Flats, which was originally a four-story cafeteria and inn. Lumberyards lined the river with freshly cut wood waiting to be shipped. John D. Rockefeller's Standard Oil Company on the East Bank was putting Cleveland on the map as an industrial power. The Flats' industrial legacy, however, would be defined by its steel mills, located along the river south of the Tremont neighborhood and west of the Slavic Village. The mills were the pillar of the city's economy and the largest consumer of water and electricity. Post-war recessions and production shifts to China and Europe hit the steel industry hard. Layoffs in the late 1970s forced many to find work elsewhere, or support from welfare programs. During this time, Cleveland, along with other industrial cities in the region like Youngstown, Pittsburgh, Detroit and Gary, had become known as the Rust Belt. LTV's repeated bankruptcies finally led to the closing their plants in 2000 (including Cleveland's plant), until investors formed ISG and resumed scaled-back operations. Over the second half of the 20th century, much of the industry and manufacturing in the Flats closed, leaving decaying buildings and persistent pollution. The chemical-clotted Cuyahoga River caught fire several times; most recently in 1969. Late 20th Century In the mid-1980s, the Flats saw a resurgence as an entertainment destination. Underground music venues appeared on the East Bank, while mainstream development first took place on the West Bank. The Powerhouse, built to power the city's cable cars, was renovated to include multiple bars, restaurants, and an outdoor music venue. Other warehouses and buildings were also renovated into nightlife destinations. At its peak in the early 1990s, the Flats had the highest concentration of bars in the Midwest, with both locally owned bars, nightclubs, and national restaurant chains lining both sides of the river from the mouth to the Oxbow bend. The Flats and Cleveland had soon become an entertainment mecca and destination for the region. The Flats Oxbow Association was formed to help redevelop the Flats, and housing development soon followed on both sides of the river, with new construction and warehouses being converted into condominiums and apartments. The Flats' 20th century heyday as an entertainment destination was short-lived. Three drowning deaths in one month
