I was thinking of a famous church today in Barcelona in Catalonia. This church has been in construction for 137 years and it is estimated that it will be completed by 2026. I remember studying it in school 50 years ago when General Franco was the dictator in Spain and the church was sitting idle with little work being done and no money to go forward. In the last 25 years things have changed and now with tourism money is fuelling a campaign for the completion of the building. Teams of architects and artists are carving stones and following the plans of the original architect Antoni Gaudi making is vision reality.
There is a beautiful blog on this project. See the link https://blog.sagradafamilia.org
I had the chance to visit the church several times between 1998 and 2012 and the progress is impressive. All the elements in the vision of Gaudi had to have a special significance on the Creation, nature and God.
