The beacon of the city's skyline, this free-standing tower is a Baltimore icon. It was built in 1911 and modeled after the historic Palazzo Vecchio in Florence, Italy. Outside, the clock is often lit in different colors to support the home sports teams, but inside is where it's at: a bevy of artists are in residence here. Every Saturday, guests can explore their studios, which amounts to 15 floors of performance, visual and literary art, for free. While there, visitors can take a tour of the clock's inner workings and enjoy the city views from way up high.
