The wonders of Old San Juan
through the eyes of an architect!


Two medieval castles, the second-oldest church in the western hemisphere and a UNESCO-designated World Heritage Site are some of the unique world-class architectural jewels you will find surrounded by the historic walls of Old San Juan. I invite you to experience these and other historic landmarks with a two-hour architectural walking tour through the streets, buildings and public spaces of this beautiful 500-year old city, the oldest within the US territory.

While in Old San Juan, enjoy a fun activity enriched with amazing and entertaining information. Discover unknown facts and hidden places that you will not find with any guidebook or tour guide in Puerto Rico. A memorable event where I will share with you my 18-plus years of experience as a historical architect -working on the study, conservation and protection of this city and this Island.

It doesn’t matter if you are a first time visitor, coming to Puerto Rico for business or pleasure, or a local resident, looking for an original and fascinating experience for yourself, for an out-of-town friend or a client. Share a walking tour with me and you will never see Old San Juan the same way again!
