Our next stop was Pisa. The most fameous thing in Pisa is probably the leaning tower but for me the most fascinating thing was the echoes in the Baptistry. When a person sings a note in that perfectly acoustical room the echoes were amazing, picking up the harmonics of the note sung to sound like there was more than one person singing.

This is a movie demonstrating the echo in the Baptistry.

Here are the photos of Pisa.
