Loveland Castle, also known as Château Laroche, is a full-scale medieval-style castle built single-handedly by Harry D. Andrews, a World War I veteran, starting in the 1920s. Constructed using stones from the Little Miami River and bricks molded from quart milk cartons, Andrews dedicated over 50 years to this labor of love. When you visit, you can wander through the castle’s towers and narrow halls, check out some old-school medieval weapons, and just soak in the quirky, one-of-a-kind vibe. It's a fun and odd little stop with beautiful gardens and a peaceful riverside spot to hang out afterward.

Reopened recently at the very site of its original discovery, the ruins of this Roman Temple of Mithras are open for public visits in the basement of Bloomberg's European headquarters at number 12 Walbrook. There are also a few other exhibitions that include both historic artefacts and contemporary artwork. Entrance is free of charge.

Bundek is an oasis where you can experience peace and nature in the very centre of the city. The lake and the big park surrounding it are great places for sunbathing, walking, or having a picnic. During summer, many events are organised at Bundek, like concerts and open cinema.
