I have to pay 9 Euro to enter Chateau de Guedelo. This is a construction site where a team of people is trying to build a castle using the techniques and materials used in the old days (without the help of technology). The daily work stops after sunset as there is no electricity. The project began in 1997 and is scheduled to complete in 25 years.
Each year hundreds of people visited the site and this place is now a popular tourist spot. According to the information I have gathered while I was there, the authority has already collected enough money from the entrance fee to build the castle. Now they are trying to slow down the work so that more money can be collected. What a good business strategy!
