Notre Dame Cathedral in Paris is considered one of the finest examples of French Gothic architecture. Construction began in 1163 under Bishop Maurice de Sully, with the cornerstone being laid. It took over 185 years to complete, with the western facade finishing in 1225 and the remaining elements being completed by 1345. Since then, Notre Dame has stood as an iconic cathedral in Paris, serving as the official seat of the Archbishop of Paris and as a sanctuary for those seeking protection.
