This museum chronicles the Portuguese influence in Uruguay. There are great maps, drawings of traditional clothing, weapons, ceramics, and more.
There is a lot of reading to be done in here, so again, you might be wishing you could understand Spanish. There´s an entire room dedicated to slavery, which was pretty interesting. We didn't take the time to read everything, as it was the last museum on our path and we were ready to be done with museums for the day, but if we had gone here first I would have spent a lot more time in here.
Of the four museums we went to, this was in the top 50%. It´s worth a visit, especially if you speak Spanish.
