Stargazing from the
Why locals love it
To be perfectly honest, people often forget there is an observatory just several minutes away from the main city square. It's open four evenings a week, if the weather conditions allow observing the night sky, and there's no entrance fee! Not to mention free astronomy workshops and popular lectures that often take place there.
Why you should visit it
If stargazing isn't your thing, I'm sure stargazing from a medieval tower, part of medieval fortification system is everyone's thing! It's a unique experience combining science, universe and history. All that in the very part of the city that gets surrounded by a lonely veil of mystery in the evenings.
If you'd like to visit the observatory in the company of your friends, better call them, since group visits should be announced.
