Built between 527 and 565 AD at the foot of Mount Sinai for Emperor Justinian, this monastery later took its name from St Catherine of Alexandria, whose remains are said to rest here. It’s more fortress than church, with thick stone walls guarding the Church of the Transfiguration, the chapel of the Burning Bush, and a monks-only library packed with ancient manuscripts. Inside, you’ll find mosaics, religious ornaments, and some of the oldest illuminated manuscripts in the world on display. Outside, don’t miss Moses’ Well and the garden with centuries of history. The place is open most mornings but closed on Fridays, Sundays, and Orthodox feast days. Still active today, the monastery holds importance across Christianity, Judaism, and Islam, and continues its Greek Orthodox traditions uninterrupted.

If you love books you have to visit Biblioteca Queriniana. The architecture of the building is amazing and should be visited for at least a quick stop by everyone. The library was built in 1705 and is located right next to the old Cathedral. Take a few steps and listen to the books.

The Berlin Wall Memorial is the central memorial site of Germany’s division. Located directly at the former border strip in the Bernauer Straße is a 1.4-kilometre piece of the Berlin Wall with a border strip and watchtower. The Gedenkstätte memorial is the last remaining stretch of the Wall as it existed during the separation era, and it conveys an impression of how the border fortifications really looked. The Visitor Center and the Documentation Center with a viewing platform are located on the other side of the street that belonged to the western part of the city. The exhibition 'Border Stations and Ghost Stations in Divided Berlin' is shown inside the Nordbahnhof S-Bahn station.

Perched above the sparkling waters where Vineyard Sound meets Buzzards Bay, Nobska Lighthouse has been guiding mariners since 1876. Originally built in 1828, this iconic beacon was added to the National Register of Historic Places in 1987. Now operated by the United States Coast Guard, the lighthouse continues its vital role in navigation while offering visitors stunning views of the coastline and nearby islands.
