Baia Castle

Bacoli, Italy

The late 15th century Baia Castle was built by the  over ancient Roman ruins thought to be the summer residence of Julius Caesar. On the 29th September 1538 the great eruption, with devastating effects for all the Phlegraean Fieldsi, caused serious damage to the Castle of Baia too. The castle was restored and enlarged by the viceroy don Pedro Alvarez de Toledo.

Today, this cliffside Aragonese castle with sea views is home to the Archaeological Museum of Campi Flegrei.

Beautiful castle on the coast. Undergoing some restoration when I visited. Houses the archaeological museum.. worth the entry even if just for the view from the tip of the castle.

Beautiful views of the area, imposing building. Nice collection of archeological artefacts found in the area. However, little history on the building itself and it has been completely renovated on the inside, so don't expect to walk into a historical looking castle/fortress. Still worthwile, however. As the views are fantastic!

Utterly not worth the walk to get to. The castle itself is ruined photogenically with excessive signage. Very little of the grounds are accessible. The museum inside has NO history about the castle itself, only a few small archeaological collections of roman and prehistoric findings from the area (which does not hold up in comparison to much better museums in Naples). Only positive thing I can say is the view across the bay is very nice.

Three layers of history on three floors - with wonderful panoramic views...

Very nice to walk the grounds and castle wall, but the museum is small and seems to be missing, well a lot. The castle is beautiful and allows a wonderful place to stroll, and overlook the bay of Pozzuoli but the museum is small (or closed?) and lacks any sort of flow or map or understanding what’s on display. Yes there are signs in English and Italian, but they describe the individual items. There’s no comprehensive understanding of the museum or totality of the collection. I was here years ago and I remember being impressed, is the other part closed for renovations or?? They have a nice restroom and a few areas to sit in the shade. Worth a visit, but with reduced expectations for the museum.

Kakesbeck Castle

Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.

The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
