You can easily walk past this church. But if you find it - you should at least take a look inside.
Not as grand as the Cathedral, however a small church, which has prayers next to each of the statues. A mass was taking place whilst I was visiting - so being respectful I just quietly looked around on the outskirts to not disturb anyone, but it didn't look like any other tourists were visiting at the time.
A few people can be seen on the steps asking for money.
