This early medieval castle offers a great view of the city from Ulus, the historic district. Within its walls, there is a small village with shops and restaurants in wooden beamed houses and the Old Turkish House Museum.

Before Opatija became a holiday resort, Volosko was the seat of the district, an important trade port and the area's administrative centre. Today Volosko has lost that importance, but not its magical appeal as a picturesque fishing village, an inexhaustible source of inspiration to artists, a haven to those searching for peace in the narrow lanes of the old town, or for a cup of coffee on the waterfront, in the unique atmosphere of the harbour. There is something very special about the view of the sea from Volosko's waterfront: the whole Adriatic seems to open up towards the south from here… When walking through the lanes in the historic part of the town, you will come across the monument commemorating Volosko as the birthplace of Andrija Mohorovičić, the world-famous scientist who first identified the discontinuity that separates the Earth's crust from the mantle. This layer is called the Mohorovičić Discontinuity, or Moho for short. He was born in the house at the very beginning of the Lungomare coastal promenade. Today Volosko is also synonymous with fine gastronomy – from typical taverns offering fish and other traditional dishes of the local area, to superb gourmet restaurants that are listed in the most prestigious international restaurant guides – Volosko offers all of that, and much more. It is only a pleasant three-kilometre stroll along the coastal promenade from where you are now standing. Do not miss the chance to pay this enchanting place a visit!

The Museum of Ethnography focuses in the Ottoman period, especially its textiles, metalwork and carved wooden doors. The museum will give you a solid understanding of Turkish history and identity.

Witnessing the age-old craft of leather treatment at the Bab Debbagh tanneries is a fascinating experience. Situated near a river for water supply, these tanneries have been operating for centuries. The distinctive odour, resulting from ammonia used in the leather-softening process, will let you know you've arrived. Unlike some other Moroccan tanneries, the focus here is on treating leather in its natural state; the dyeing happens elsewhere. Visiting the site can be a bit tricky due to the presence of unofficial 'guides' demanding payment. If you prefer a hassle-free experience, consider hiring a certified guide as part of a medina tour. Otherwise, prepare to navigate past these unofficial attendants by offering a small tip and insisting on entering without their assistance.
