...because there really isn't too much else you can do besides look at it and snap a photo, but at least it is in an area by a lot of other nice things to do. It is especially nice to see it from the view of the palace from a restaurant, nice options include Casi Clari or the Pirata Bar.

It was recently reopened to public because of major reconstructions, paintings and facilities updates. For example, the face over the Asuncion Bay considered its historic orientation. All the work demands millons of dollars and if you visited it before, a new visit is strongly recommended. Please check day and hours of public openings and enjoy sun, friendly locals, and nearby good food.

Not visitable or photographable. Surly armed soldiers outside and pickpockets and thieves everywhere. Don't go, day or night.

Asuncion needs to up some of their police presence - they are around but around here it was just dodgy. Nice old buildings (nothing special if been to other South American cities) but just an unpleasant element hanging around. Even got offered to buy a taser here... I politely declined.
