Today it is a private residence, but in the past it was the railway station of the village of Grisignana/Groznjan

A peculiarity of this gallery is a strange concrete scaffolding inside it.... the explanation is strange, because it is a disused company for the cultivation of mushrooms.

This was our third time there, and each time we were lucky enough to have musicians playing in the evenings, enhancing the already special atmosphere of this little town. Unforgettably beautiful...

Piran, Slovenia's most beautiful coastal town, owes its development to its traditional salt pans, where high-quality salt is still harvested today. The town impresses with its medieval ring wall, church, and numerous cultural attractions.

The tunnel is a hiking and cycling path. It's lit. However, you still need to be careful. There's a lot of traffic (mopeds, e-scooters, etc.).
