There is a large building in downtown NOLA called One Shell Square. It houses a lot of Shell employees, but also, a lot of law firms. The Shell plants are in surrounding parishes, as we call them. Chevron also has offices in the NOLA area, a very nice one in Covington, known as the North Shore, where the public school system is excellent and quality of life is much better. But it does not hold the cultural appeal of NOLA and the people are the type you'd see in the Real Housewives of Orange County. Many professionals make the 90 minute commute from Covington to work in the Central Business District of NOLA, which is mainly some "skyscrapers" and abandoned buildings. But, because the courthouses are located there, you will find the majority of law firms located in that area of the city, and their clients, the oil companies, have many offices there, though very little, if any, of the "hands on" work is done there.
