During my Paris trip, I took a bus tour to the Chartres cathedral with its famous deep blue stained glass windows. It was a very good tour. The cathedral is one of France's UNESCO world heritage sites. The cathedral is over 800 years old and the floor still has the original maze for pilgrims to walk on. The town itself is very charming with many people enjoying the outdoor cafes. It reminds me a bit of Quebec City with its steep streets lined with old houses.
