The Peace Altar Museum, right next to the Peace Altar site, is a relatively modern building. The museum is not expensive but the ticket is quite expensive. It mainly contains some collections of the Peace Altar. Unfortunately, the guide is not in Chinese.More
It's a must go in Rome, tickets are free for EU students
This monument was built after Augusto emperor will. The museum that contains Ara Pacis is the first architectural space that has been built in the Centre of Rome after the Second World War. The architect is Richard Meier. Before Meier intervention the monument was just there, under the rain, sun, wind. Now it is protected by big glass walls that still let the monument be part of the city as before.
Ara Pacis: the story of Ancient Rome!
I'm not sure exactly how cost effective this attraction is. Ara Pacis is certainly important and cool, it just seems like you get very little of a building for the ticket price. Sure, it's preserved well (the building protects it from the elements) and it's important to fund this preservation. Best to come during an art exhibition and opt for that as well. I saw a great exhibition after staring at the Ara Pacis for a half hour and it was a great afternoon.
The Ara Pacis Museum opened in the spring of 2006, and was built to house a more than 2,000 year old "Altar of Peace" that was used (paradoxically) for sacrifices. The museum was designed by the international architect Richard Meier and has been subject to much controversy and criticism.
