All the monuments posted are just great.

Greek architecture was based chiefly on the post-and-beam system, with columns carrying the load. Timber construction was superseded by construction in marble and stone. The column, a unit human in scale, was used as a module for all of a temple's proportions. The Doric order, probably the earliest, remained the favorite of the Greek mainland and western colonies. The Ionic order developed in eastern Greece; on the mainland, it was used chiefly for smaller temples and interiors. The greatest Greek architectural achievement was the Athens acropolis.

Here are the ruins that were left over of the city of Sarmizegetusa, which is high in the Carpathian mountains, after it was destroyed by Emperor Trajan when he finally conquered Dacia(modern day Romania) in 105AD.
