Founded in the 7th century by St Willibrord, the patron saint of Luxembourg, the Abbey of Echternach contains a fascinating scriptorium — once the most important in Medieval Europe — in its cellar, with manuscripts dating as far back as the 11th century. Part of the abbey complex, the Basilica of Saint Willibrord contains a crypt with the saint's holy remains. A dancing procession that draws visitors from all over the world (Saint Willibrord Pageant) is held in the town annually on Whit Tuesday.

Sun Studio is often called the "Birthplace of Rock 'N' Roll," and for good reason. This is where Elvis Presley, Johnny Cash, B.B. King, and countless other legends recorded some of their earliest hits. Opened in 1950, the studio still runs recording sessions at night, but by day, it offers tours that let you stand where music history was made.

Al-Rajhi Grand Mosque stands as one of the largest places of worship in Riyadh. Its vast prayer halls can accommodate over 20,500 worshippers, and the complex functions as a comprehensive Islamic centre with libraries and educational facilities. While entry is reserved for Muslims, the impressive exterior architecture, particularly striking when illuminated after dark, makes it a notable city landmark. The mosque's scale and community role underscore its significant position within the capital's religious and cultural landscape.
