Hi, Animo!
I am a student of the University of the Philippines doing my thesis on corporate architecture during the American colonial period.
It is with much interest that I read your post on the Aduana. Just a clarification, is the picture I posted below the same building that you were referring to in your post? Also, would you be kind enough to refer me to the archival source of the 1796 instruction that directed that the Aduana be located inside Intramuros. It might prove useful in my research
By the way, although unrelated to my study, your post on the history of Philippine aviation was not only interesting but also showed very good research and grasp of the subject.
Keep it up!
