For the whole of the summer, the Rialto Square Theatre has hosting tours of the building two times per day during the week. Each tour includes a pipe organ concert at the end of the tour, which costs $5.

The daily tours, which highlight the history of the theatre, take participants behind the scenes and give information about how a stage and theater show functions, will end on Aug. 31. The Rialto will then go back to holding tours at 1:30 p.m. every Tuesday, but those tours will not highlight the theatre's pipe organ.

Here is what I learned about the Jewel of Joliet when I went on the tour at noon on Tuesday.

• 200 - approximate number of crystal light fixtures in the theater the year it was built. Not there are slightly less.
• 1926 - year the Rialto was built
• 250 - number of light bulbs in The Duchess, the chandelier in the main vestibule
• 2 - number of times per year The Duchess is lowered to the floor for a total cleaning
• 45 - number of minutes it takes for The Duchess to get to floor-level
• 300 to 350 - number of guests the Rialto can fit for a sit-down dinner wedding reception
• 16 number of feet tall of the largest pipe in the pipe organ. The largest pipe is made from wood
