There's a chance that you won't be blown away by the beauty of the Columbus Lighthouse. El Faro a Colón, as the locals call it, is built in the shape of a cross, and some former visitors described it as downright ugly.

Still, this is a historically significant attraction that houses the purported remains of Christopher Columbus. Additionally, travelers can also find various exhibits — like a vehicle once used by a former pope — as well as several libraries. (Much of the interior, though, lies unused.)

You can visit the controversial lighthouse, located in the Sans Souci part of town, anytime between 9 a.m. to 5:30 p.m. on any day but Monday. Admission will cost you about 20 Dominican pesos (or the equivalent of $0.44 USD). Children ages 11 and younger can enter for approximately RD$5 (or about $0.11 USD).
