Reportedly the world's oldest library, first established in Fes over an entire millennium ago (9th century), the Al-Qarawiyyin Library recently opened its doors to the public once again following a restoration effort. The library still belongs to Qarawiyyin University, the oldest continuously operating university on Earth.

The Attarin Medersa, a former koran school, might not be the biggest one in town but, instead of an impressive size, quite stunning for many reasons. The different tiles in lovely colours, and the overall architecture design make for a place that is a must see on your itinerary.

The MacRitchie Reservoir is Singapore’s oldest water reservoir. Its main purpose is to collect rainwater and provide drinkable water to Singapore’s residents. Additionally, the reservoir is the central feature in MacRitchie Reservoir Park. The MacRitchie Nature Trail is a series of boardwalks that vary in length and take you through the tropical rainforest. The TreeTop Walk — one of the park's main draws — is a suspension bridge that gives you a bird’s-eye view of the forest below. On your walk, you will definitely see some monkeys. They are definitely cute, but can be a little naughty, especially if you are carrying any food.
