The Bromo Seltzer Arts Tower, once Baltimore's tallest building, hosts a state-of-the-art studio space for literary and visual artists. The area is open once a month for guests to visit the studios or purchase artwork (check the website for schedule). The tower itself is unique. Constructed in 1911, it was built by Isaac Emerson and modeled after the Palazzo Vecchio in Florence. (Emerson was also the inventor of the headache remedy Bromo Seltzer, hence the tower's name.) While the 51-foot revolving blue Bromo Seltzer bottle perched on the top of the tower was removed in 1936, the original clock still displays 12 letters—BROMO SELTZER—instead of numbers.
