Worthington, just north of Columbus, is one of the older cities in Ohio, having been founded in 1804, and still preserves a primarily Federal architectural landscape. Many of the buildings along the main road through town, High Street, and many of the surrounding homes date from the 1810s to the 1850s. The Worthington Historic District on and around the Village Green is one of the best-preserved Federal streetscapes in the state, and the district includes the oldest Masonic temple west of the Alleghenies — the New England Lodge, built in 1820 and now housing a small museum — and the Buttles Building, the oldest residence in town dating from 1811.
Worthington also holds the only pontifical college outside of Italy, the Pontifical College Josephinum, founded in 1888 and reporting directly to Rome. On the outskirts of town is the Ohio Railway Museum, which contains several streetcars, interurbans, and railway cars and locomotives, some of which still run on operating days. A more recent attraction is Rush Creek Village, a neighbourhood built primarily between 1956 and 1960 based on Frank Lloyd Wright's Usonian principles. On the western edge of town, close to the Olentangy River, Jeffers Mound is a surviving Hopewell burial mound dating back roughly two millennia.
