The city was named for railroad builder Arthur E. Stilwell. It is the home of Lamar State College and a year-round fisherman's destination. The average temperature varies from 55 degrees in winter to 82 in summer. The convention and visitors bureau offers a Waterways Guide, which provides information on area freshwater and saltwater fishing. From the port, view the harbor and the largest gantry crane on the Gulf Coast, and see the Rainbow and Veterans' memorial bridges. The Rainbow Bridge's 176-foot clearance height resulted from a requirement that any U.S. Navy ship at that time (1938) could pass under. Veterans' Bridge, with 143-foot navigation clearance, is the first cable-stayed bridge on Texas highways. Port Arthur comes alive during Mardi Gras with a family-oriented pre-Lenten celebration.
