As we stroll through our communities, we often admire the architecture that surrounds us. Some buildings, however, have taken much longer to complete than others. These constructions not only reflect our history but also our determination and resilience. From cathedrals that span centuries to modern skyscrapers that faced delays, let’s explore notable buildings that are still in the process of being constructed or took an astonishingly long time to finish.
#1: La Sagrada Família (Barcelona, Spain)
Construction of La Sagrada Família began in 1882, and remarkably, it is still ongoing today, over 140 years later! Designed by the famous architect Antoni Gaudí, this cathedral has become a symbol of Barcelona. While it attracts millions of tourists each year, the slow construction process is due to the detailed artistic vision Gaudí had.
