On campus you’ll find the I.P. Stanback Museum and Planetarium (803/536-7174, www.scsucrash.blogspot.com , free), a 16,000 square-foot complex with a good regional art gallery, a steady schedule of events, and a 40-foot dome in the planetarium. Call ahead for hours.
An even older historically black college, first in the state, is Claflin College (400 Magnolia St., 803/535-5000, www.claflin.edu ), just southeast of downtown. Founded in 1869 at the height of Reconstruction, Claflin has its own historic district on campus, including the 1898 Arthur Rose Museum (formerly the Lee Library), a nice Victorian built of bricks fired on campus.
It now has a college-related collection, open during regular business hours. Tingley Memorial Hall, with its distinctive cupola, was built in 1908 and is on the National Register of Historic Places.
From Edisto Gardens  travel north on Russell Street a few blocks. The stretch of Russell between Broughton and Church Streets is the main business district, with several well-preserved commercial buildings such as the turreted, 1904 Louis Building (1198 Russell St.) and the 1941 Bluebird Theatre (1141 Russell St.), now home of the Orangeburg Part Time Players (www.optp.org ).
A short ways off Russell you’ll find the Briggman House (1156 Amelia St.), a.k.a. “Briggman’s Folly,” built in 1850 by Orangeburg’s first mayor, a German immigrant named Frederick Briggman, and held together with wooden pegs.
