The War Room is located near the Danger Room. It is the 'operating center' of the X-Men. This is where briefings are given, missions are planned, and meetings take place.

There are various computers and monitors around the War Room, each with their own function. The War Room monitors news feeds from every news network on television and radio, and scans every known frequency for reports on events occurring around the world. Thanks to the artificially intelligent computer program Cerebra running throughout the mansion, the X-Men don't need to scan 24/7. If Cerebra picks up something, it will notify the X-Men through their communication links.
