This cathedral in Chile is one of Gustave Eiffel ‘s work… it was made at the end of the 19th century after an earthquake destroyed the previous church. It’s called the St. Mark’s cathedral.
It has an architectural design and is unique to the work of Eiffel ! (yes, the one which tower in Paris is holding his name) 😍
