A distinctive element of the Cathedral is the asymmetry of its lateral towers. I have always wondered what the reason was for not building them the same.
The Plaza de la Catedral is a must-see when you want to get to know Havana. I have visited it many times and I always find it interesting.
I have the answer for you...
The asymmetry is primarily due to the fact that the budget ran out, and they couldn't make them equal. Secondly, they couldn't take more land to allow the water to flow through the adjacent streets.
In fact, if you have the opportunity or remember, the buildings on the sides are very, very close to the towers, which reinforces what I'm telling you
