DOWNTOWN. Built in 1851 in Lucas Place, the city's then-ritziest neighborhood, this three-story townhouse was home to the family of Robert Campbell, an immigrant entrepreneur and one of the state's wealthiest men during his life. Following a $3 million restoration, it has been returned to its high Victorian glory, full of family possessions and artifacts. Replica textiles, original lighting fixtures, authentic furniture, and lots of decorative arts create a scene of century-old opulence, offering a glimpse into St. Louis's early days.

DEFIANCE. Appalachian pioneer Daniel Boone settled in Missouri towards the end of his life and lived in this four-story house with his wife and extended family. Remarkable even now, the structure boasts a ballroom on the top floor and limestone walls that are 2½-feet thick. Behind the house, a living history village features a chapel, schoolhouse, woodworker's shop, and milliner's shop; more additions are planned. Tours commence with a short film about Boone, after which groups explore the house and Boone's personal possessions.

A memorial to all of the oppressed Jews during the Holocaust, this museum offers guests a chance to reflect on and discover the reality of history.
