If you happen to stroll through the many alleys in town, you might stumble upon the Odeon. Only a few steps away from the main road, this Roman theatre was discovered in 1892 underneath buildings constructed upon it over the years. Its remains stand out from the rest of the city, a testament to the long gone Ancient Roman Era.

A bit outside Verona, but worth the trip if you’re into natural history. This small two-floor museum focuses on fossils from the nearby hills, which used to be a tropical sea. You’ll see fish, insects, plants, even reptiles—some surprisingly well-preserved. The collection isn’t huge, but it’s solid and well curated.

Monserrate is a dramatically high mountain over 3,152 metres (10,000 feet) high that dominates the city centre of Bogotá. You can reach the top on foot, but be warned that it won't be the easiest trek of your life because of the altitude. Alternatively, take the cable-car or the funicular. They will safely deliver you to the church with a shrine devoted to El Señor Caído with astonishing views over the city. If you are superstitious, be warned: Colombians believe that couples who visit Monserrate together will never get married.
