From the articles and the documents of the archives we can assume the following construction dates or periods of each building:
Classical Buildings:
1) Block A: Caldwell House built in 1842, extended in 1852 by Father Beurrel.
2) Block F & C: Open Galleries. There are no written documents describing their construction, but according to their architecture and construction details, they are certainly from the middle of the 19th century, but with many modifications during their existence.
3) Block D: Orphanage built probably between 1860 and 1890.
