Opened in 1863, Ford’s Theatre is best known as the site of Abraham Lincoln’s assassination. You can tour the theatre, visit the museum, and learn about Lincoln’s life and legacy. The adjacent Petersen House, where Lincoln died, is part of the experience.

Step into the shoes of a spy at the International Spy Museum, which holds the largest public collection of international espionage artifacts—from gadgets to disguises—and documents the tradecraft, history, and contemporary role of espionage. It’s interactive and entertaining for both adults and kids, but timed tickets are required, especially on weekends.

Venetian rule in Santorini extended from 1207 to 1580, and the last vestiges of this historical period live in the castles that dot the entire island. Five fortresses can be found in Santorini in Oia, Pyrgos, Emporio, Akrotiri, and Skaros, which have been partly demolished by the earthquakes that shook the island in the 15th and 16th centuries. Skaros is probably the most important and well-preserved among the five castles, built on the peak of the namesake rock to protect the village from pirate attacks. The ruins of the once magnificent fortress can be reached on foot from Agios Georgios church in Imerovigli, connected to Skaros by a 0,5 km walking trail and a long stairway.

This cliffside hike is one of the best ways to take in the island, spanning approximately 9 km from Fira to Oia, with Imerovigli and several smaller villages in between. It’s not difficult, but parts of it are steep, rocky, and exposed, so bring water, sturdy shoes, and start early to avoid the midday heat. Expect churches, caldera views, and the occasional detour through quiet paths. It takes around 3–4 hours, depending on pace and photo stops. Ending in Oia means you can reward yourself with dinner and a view—just be ready for the crowds if you hit sunset.
