It was a gated entrance built to secure access to the Parthenon and other buildings on the Athenian acropolis.
While not intended as a fortification, it controlled access so that ritually unclean people could be denied access to the temples. It also acted as a barrier to criminals and runaway slaves gaining access to the temples to claim sanctuary. And as the state treasuries were kept on the Acropolis under protection of the gods, there was that additional security requirement.
Propylaea - Munich - was created in 1862.

The Acropolis is a hill, so it was not built. Being fortifiable, it was the original site of Athens (as was the Acropolis of Corinth and so on). Various temples were erected there over the centuries, culminating in the present buildings constructed in the second half of the 5th Century BCE.
3 ancient temples: the Parthenon, which is well known, as it is enormous, the Erectheion, and the temple of Athena Nike. There is also the large entrance way which is called the Propylaea.
The Parthenon (the really big one) the Erechtheion, and the temple of Athena Nike (which is really rather cute and little). There is also the Propylaea (the entrance way) which isn't a temple but it is an impressive building none the less.
The Acropolis of Athens has more than 20 structures or remains of structures, and it's difficult to determine which ones would be the "main" ones. However, important and noteworthy to archaeologists are the following structures: the Parthenon, the Propylaea, the Temple of Athena Nike and the Erechtheum.

I assume you mean "built in" not "in built." A built in oven is an oven that is not mobile, and it is built in to the wall of the kitchen.
