Hi Mipiano, certainly the joke was great, a few of them let out a scream of fright linked with surprise that was even more hilarious, I remember and I can't stop laughing. That is a beautiful fortress and has been very well preserved despite the years and its use as a venue for numerous events. There are other fortifications just as interesting although not as majestic as this one.
In a few days, happy 16th birthday to your daughter :)
Thanks ;D
