Downtown Pittsburgh is best seen from a bird's eye view, or better yet, the Duquesne Incline. For $5 round trip, an old style cable car takes you up/down an incline for phenomenal views of the city that sits on a peninsula and is connected to its surroundings by a vast amount of bridges.
The University of Pittsburgh has an assortment of unique nationality classrooms located on campus at their Cathedral of Learning building. It's a self-guided tour that includes a handheld audio device that provides a narration for each room on the first floor. The room themes range from French, Italian, Russian, Japanese, and so on. Other than the history and aesthetics of the room, it's fascinating that they are still used as active classrooms. The Cathedral of Learning building itself is worthwhile to see on its own with the beautiful gothic architecture throughout the exterior and interior.
