1. “The Central Library downtown (1301 Olive Street, 314-241-2288) is a gem hiding in plain sight. Step inside under the stunning architecture outside and prepare to be awed by the ornate details and welcoming public spaces inside. The $70 million renovation in 2012 is something every St. Louisan — and visitor — should make a point to see.” – Francis Slay, mayor of St. Louis
