Savannah: What to See & Do: Architecture: Architectural Savannah
A SCAD grad, Stalcup has been leading architectural walking tours of Savannah since 2004. He offers several tours a day beginning in Washington Square ($20 per person), but reservations must be made in advance. Custom tours focusing on specific eras, architects or interests start at $300 for fewer than 15 people or $20 per person for larger groups. It is also possible to buy a copy of his book online, if you want to meander on your own.
