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

Two medieval castles, the second-oldest church in the western hemisphere and two UNESCO-designated World Heritage Sites are some of the unique world-class sites you will find within the historic walls of Old San Juan. I invite you to experience these and other unknown historic buildings, urban spaces and features in a unique architectural walking tour through this beautiful 500-year old walled city -the oldest within the US territory.

While in Old San Juan, enjoy a fun cultural activity enriched with amazing and entertaining information. Discover unknown facts and hidden places that you will not find with any self-guidebook or tour guide in Puerto Rico. Experience an exclusive tour where I will share with you my 20-plus years of experience as a historical architect and preservation expert working on the study, conservation and protection of this city and its fortifications.

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!
