1. The Mercer Williams House Museum is a historic house located in Savannah, Georgia. It was designed by architect John S. Norris and built in the Italianate style in 1868 for General Hugh W. Mercer, the great-grandfather of songwriter Johnny Mercer. The house has a rich history and has been occupied by several prominent Savannah families over the years.

One of the most interesting parts of the house’s history is its connection to Jim Williams, a Savannah restoration expert and antiques dealer who owned the house from 1969 until his death in 1990. Williams was also the central figure in the book and movie \"Midnight in the Garden of Good and Evil,\" which chronicled the murder trial following the shooting of Williams’ assistant in the house.

Today, visitors to the Mercer Williams House Museum can see many of the original furnishings and artwork owned by Jim Williams, as well as other decorative arts and artifacts from the 19th and 20th centuries. Guided tours are available, and the house is a popular destination for tourists and history buffs alike.
