Pobiti Kamani, also known as the Stone Forest, is a fascinating natural phenomenon featuring numerous limestone pillars, some as tall as 10 metres. These formations include hollow and solid cylinders, truncated cones, and scattered rocks and cliffs. The origin of this unique landscape remains a mystery, although evidence of human life dating back to the Mesolithic period has been discovered here. It's an intriguing destination for nature enthusiasts and those interested in geological history. If you visit during the summer, make sure you bring water, a hat, and sunscreen, as the area can get quite hot. The Stone Forest is accessible by car or public transport.

Just outside Piazza Duomo lies one of the oldest Jewish cemeteries in Europe. The cemetery presents an extraordinary historical artistic repertoire: from the parallelepiped burial mounds of Hebrew tradition dating from the 17th to 18th centuries to the Liberty styles dating back to the 19th and 20th centuries.

This masterpiece of Italian Gothic architecture is most famous for what it’s missing—a roof. The abbey was built in the late 1100s and has been a dramatic-looking ruin for centuries. It’s open to the sky now, but still feels grand in a stripped-back kind of way. Just up the hill, the Rotonda di Montesiepi is worth a quick stop too—inside you’ll find a sword embedded in stone, tied to the story of Saint Galgano.

Founded by governor Sir Henry Conway Belfield in 1917, this Gothic-style cathedral is one of the most important buildings of the Anglican Church of Kenya, and a prominent landmark of the British-Kenyan relations stemming from the 19th century.
