holy crap, I have always wanted to visit there. It is amazing what they accomplised. Most all of those ruins are made out of rocks/ boulders cut to laser precision. Even engineers of today admit it would be damn near impossible to recreate what they did thousands of years ago even with todays technology.
Yes, that's true. The ruins are so well preserved. It's amazing! This place is really well worth a visit. You feel huge respect for those ancient engineers.
