Sofiero Castle was one of the Swedish royal family's country mansions. It was originally a Scanian farm called Skabelycke, bought in 1864 by Crown Prince Oscar of Sweden and his wife Sophia of Nassau. The first one-story palace was completed in 1865. It was expanded to its current size between 1874 and 1876, after crown prince Oscar had been crowned king Oscar II of Sweden and Norway.
In 1905, Oscar II's grandchild Prince Gustaf Adolf, future King Gustaf VI Adolf, and his wife, crown princess Margaret received the palace as a wedding gift. They renovated the palace and started the large Rhododendron garden for which the palace is known today. Prince Gustaf Adolf become king in 1950 and until 1973 Sofiero was his and his second wife Lady Louise Mountbatten's official summer residence. It was supposedly the King's favorite place and upon his death, which occurred in Helsingborg, he left Sofiero to the city of Helsingborg so that the general public could enjoy it as much as he had.
The main attraction today is the very large gardens with a wide range of local (and other) plant life, stretching to the shore of Oresund. The Rhododendrons are especially noteworthy, consisting of almost 500 different varieties. The park also holds a small collection of modern art. During the summer the large grass areas are sometimes used for large outdoor concerts with national as well as international stars. The castle itself is today used as restaurant, cafe and at times as a gallery.
References:Herceg Novi was founded (on a former small fishing village, existing since Roman Empire times) as a fortress in 1382 by first Bosnian King Stjepan Tvrtko I and was called Sveti Stefan or Castelnuovo. The Turks conquered Herceg Novi in 1482, and ruled for 200 years, until 1687. However, there was a short pause between 1538 and 1539 when it was held by the Spaniards before they were defeated in the Siege of Castelnuovo. Turkey ruled again until 1687, from then until 1797, the town was ruled by the Venetian Republic.
The Herceg Novi old town is amazing. It is on a fairly steep hill that leads all the way down to the sea. Wandering through the small stairways to the various plazas and fortresses is a many hour adventure.
