Admission to the archives is free (you do need to pass through a metal detector) but there's not really much to look at. There's a small exhibition on Murillo, the Spanish baroque painter, on the main floor and a few maps and other historical objects on the second floor. Some of the interior architecture is interesting including the main staircase and one of the archives room you can see on the second floor. Not worth going out of your way to see.
