This place is awesome. A camera cannot capture its grandeur but my few photos will give you an idea. The builders used 57 different types of marble, all from Uruguay. The guided tours are in either Spanish or English and the tour guides will give you a great insight into things of significance in the building and also some local history. The cost is minimal - great value. Check tour times, there are only one or two tours per day. I have lived in Montevideo for a few years and just discovered this gem this year. It is certainly on my list to recommend to every friend who visits.
