If you're interested in the architecture of New Orleans or a self-guided walking tour, then start here. The welcoming Preservation Resource Center, located inside the 1853 Leeds-Davis building, offers free pamphlets with walking-tour maps for virtually every part of town. Helpful staff shares information about everything from cycling routes to renovating a historic home. Check the website for details about the Shotgun House tour in March and the popular Holiday Home tour in December. The neighborhood brochures are also available online.
