A'dam is the iconic and controversial tall building next to the Eye Film Institute and opposite Central Station. It calls itself "a tower of many talents": you can grab a bite, work in a coworking space, rave at the club and spend the night at the hotel here. The tower hosts some major creative labels, so the crowd is always interesting. For some adrenaline, check out the A'dam Lookout — an observation deck with a panoramic view of Amsterdam, an interactive exhibition and free audio tour about Amsterdam’s history and culture. A swing that lets you dangle your feet off the edge of the building is the cherry on top.

The Palacio Real de Madrid — the official residence of the Spanish royal family in the city — is Europe's largest royal palace, boasting a whopping surface area of 135,000 square meters and a staggering 3,418 rooms. This architectural marvel is not only visually stunning, but also features spectacular outdoor gardens and exquisite frescoes, furnishings, and paintings within its walls. Originally constructed in 1764 as a replacement for the Alcázar castle, which had been destroyed by fire three decades earlier, this magnificent edifice is a must-see attraction for visitors to Madrid. Nearly the entire palace is open to the public, including the Armoury and Pharmacy.

Walk (or bike) along the Corniche to witness the leisurely flow of life by the Mediterranean; if you head south towards the Raouche neighbourhood, you will eventually come to one of Beirut's most iconic natural sites: the Pigeon Rocks, limestone formations jutting out of the sea. Come at sundown for shisha with a view.
