NEW YORK — Grand Central Terminal is featured in lots of movies, from Hitchcock’s “North By Northwest” to the animated “Madagascar,” and with good reason: It is a magnificent Beaux Arts monument, one of the finest examples of civic architecture in the country. In February it will celebrate its 100th birthday.

My wife and I recently took the official audio tour of Grand Central Terminal. We paid $7 each at the ticket window on the main concourse and were provided with headphones, audio player, and a map, which took us on a 21-stop tour inside, below, and outside the station. We went at our own pace, taking about 90 minutes to complete the tour.
