This museum is sold as a demonstration of the practices that were utilized during the Spanish Inquisition of Columbia. To accomplish that goal the first floor of the museum provides a series of torture devices that were apparently in use at the time of the Inquisition. However upon closer review many of the devices were actually not used and most of them are reproductions. What is even worse is that there is very little history provided about the Inquisition itself.
Now on the third floor there is a more useful floor that goes over the history of Cartagena. The individual sections are in Spanish but there are summaries provided in English. There are also guides provided that can be hired to tell you more detail about the history of the museum.
The cost of the museum was quite high for what you get. In summary, there are much better places to see in Cartagena that are far more interesting. I realize that some folks might disagree with this but there are far better museums in Columbia to see than this one and the name as well as the advertising is done around town to attract tourists.
Unique Suggestions: If you are in this museum and find the first floor boring and disgusting, run on up to the third floor and get a quick lesson on the history of the City.
Fun Alternatives: Go to Plaza Bolivar, walk around the walled city or take a tour of San Felipe de Barajas Fort.
I simply could not find one. I was directed to the Avianca office, the national airline of Colombia just outside the wall, however when l did q up they told me they did not sell stamps, gave me directions on where to find a post office. My friends could not find it and eventually we gave up. I did hear that the price of a stamp was simply way over the top, l just wanted until l got to Miami to post my cards.
Fun Alternatives: Wait until you get home.
I know most travellers keep their wits about them but l have heard of so many people getting ripped off by the local con artisits who offer to change your money. Cali in central Colombia turns out the biggest forgeries of Colombian money. What the con artists do is give you a great rate and when you hand over your money they give you false pesos. You might think your getting a great deal but how is it possible to beat the banks rate. You will be approached constantly by these con men. Stay miles away from them.
Fun Alternatives: Go to a bank. Inside the walled city you will find many who will change your money and there are also many ATM machines around and a few have guards outside to make sure no one follows you in to rob you.
