I would like to climb the Torre Guingi. It sounds like they sell timed ticket but I can't find where to buy them. Any advice? Thank you!
This is the website for buying tickets. The website is not cooperating with me at the moment. On Chrome, it defaults to a date in August and won’t let me pick dates before then. On Safari and DuckDuckGo, it will only let me pick yesterday and then tells me there are no tickets left. You may want to try the website during daytime/working hours in Italy in order for the website to work.
If you can't get tickets for the Torre beforehand I wouldn't worry that much. When I was there a small line of people seemed to constantly be buying them and going up. There are actually 5 claimable towers in town so there are even other options - although they won't give you the ability to say "I climbed that" whenever someone looks at the classic Lucca photograph.
Enjoy,
