Built in the 13th century and dedicated to the Assumption of Mary, the Basilica di Santa Maria Gloriosa dei Frari, usually called the Frari, is the largest church in Venice and an important example of Venetian Gothic ecclesiastical architecture. It holds many masterpieces of Venetian art from the Renaissance period, which is simply a delight for the eye. Titian, the most renowned member of the Venetian school of painting of the 16th century, not only has paintings here, Assumption of the Virgin (1516–18) and Pesaro Madonna (1519–26), as this is also his final resting place.

Built between 1906 and 1912, Casa Milà, commonly known as La Pedrera ('The stone quarry'), is a modernist building in Passeig de Gràcia and the last private residence designed by Catalan architect Antoni Gaudí.

So get inside Casa Milà to discover another one of Gaudí's unconventional architectural creations.

Its mosaics of natural elements, such as birds, palms, and plants, along with the dome and the unusual design, make it the perfect setting for couples to exchange their wedding vows.
