Gaudí’s masterpiece in Barcelona, La Sagrada Familia is a gorgeous church that attracts over 3 million tourists each year. The construction of the iconic church started in 1882 and is projected to finish in 2026. The intricate exterior looks amazing and features 3 different facades: the Nativity facade, the Passion facade, and the Glory facade. The interior of this Catholic basilica is even more breathtaking. Plan your visit in the late afternoon when the sunlight seeps through the stained glass on the west side. It’s a truly magical sight to see the tall chamber light up in vibrant rainbow colors. You can also take a tour to go up one of the finished towers and enjoy panoramic city views from the top.
