The first edition of the Casco Antiguo tourist site PDF was issued on 16th March 2016. You can purchase the PDF using the Paypal button located on the Casco Antiguo page under the Panama Sights drop down menu.

The information is all available on the website, however the download will enable you to read it all offline as you walk around Casco Antiguo. If you are able to print anything, get the map on page two at a decent size, otherwise you should be able to recognise the sights from the pictures.
