Before the parish had a proper courthouse, it had a tree. The Sallier Oak on the grounds of the Imperial Calcasieu Museum in Lake Charles has stood for over 300 years — longer than the city itself, longer than the lumber boom that built it, longer than the fires and hurricanes that periodically leveled everything around it. The museum it now anchors, opened in 1963 as the regional keeper for five parishes, holds the through-line: Atakapa-Ishak culture, the longleaf pine era, sulphur, oil. Fifty miles north in DeRidder, that same Imperial Calcasieu territory produced something stranger — a Collegiate Gothic jailhouse built in 1914, possibly the only one of its kind in the country, connected by an underground tunnel to the Beaux-Arts courthouse beside it. The jail earned its name from executions conducted off its interior spiral staircase. It's listed on the National Register. It still gives tours. Southwest Louisiana keeps what it builds.
