Château de Guédelon 盖德隆城堡

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.
