The Huys Dever is a small castle probably built shortly after 1375 by Reinier Dever or d'Ever, a member of an old noble family from Holland. The castle was a typical stronghold that was at one time situated on the edge of a lake called the Lisser Poel (since poldered in) that itself was in connection to the Haarlemmermeer (itself a polder since in 1853). In 1630 a stately home was built on to the tower and became a summer residence, but after the Haarlem Lake was poldered in the 19th century it fell into disuse and became a ruin. In 1973 restoration began and the roof was built in the manner of 16th century carpentry.
The building houses a small archeological museum with finds dug up in the former moat around the building. It has been voted a very important rijksmonument for its early medieval remains. The building is open to visitors.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
