Lucca. the walled city

Have driven through the city so many times but never ventured beyond the walls.
This is a stunning town and housed a thriving market, wonderful architecture, and a culture of its own.
One of the towers even has trees growing from the top.
Poor Kath though. She has been eaten alive by the mosquitoes and was walking in pain.
Not even a giant steak could quell the pain, so time to go off to the chemist for some antibiotics over the counter?
