Nylars Church (Nylars Kirke) is a round church built around 1165. The church was dedicated to St Nicholas. Originally designed for a defensive role, the solid structure contains a series of 13th century frescoes, the oldest of Bornholm's four round churches.
The three storeys are built of fieldstone and with window and door frames of limestone. The original defensive systems are largely intact. The decorated south door is well preserved. The porch is from 1879. The church first belonged to the Archbishopric of Lund, then came under the Danish crown at the time of the Reformation. In the 19th century, it became fully independent.
The three-storey circular structure with a diameter of 11 metres was originally unlimed. The oval-shaped chancel and its apse were constructed at the same time as the nave. Unlike the round churches of Østerlars and Ols whose masonry is supported by buttresses, Nylars is solidly constructed with walls up to 2 metres thick. Originally the church had two doors, one for men and one for women. The northern women's door was first replaced by a window in the 19th century, then completely bricked up in 1973. Measuring only 52 by 27 cm, the small window in the northwest corner behind the stairs up to the gallery is the only completely original Romanesque window in Bornholm's round churches.
The lower section of the separately-standing bell tower was probably once used as an entrance gate. Remains of the west door can still be seen in the west wall. A niche on the upper floor probably contained a door leading to a staircase as at Østerlars. The belfry is a later half-timbered addition. There are two bells: the smaller one is from 1702 and bears the stamp of King Frederik IV while the larger bell was cast on Barnholm in 1882.
Like the other three round churches on Bornholm, the nave is covered by a ring vault supported by the heavy central pillar built of limestone from Limensgade near Aakirkeby. The apse, lined with limestone flags, has a high half-domed vault in which five holes in the shape of a cross can be seen. The gallery and pulpit, originally from 1882, were decorated by Poul Høm in 1973 in tones reflecting those of the church's frescos. In 1972, Høm also completed the little stained-glass window depicting a timeglass located behind the pulpit. In 1882, when the whitewash was removed from the interior, a 13th-century fresco frieze was revealed around the top of the central pillar. On a blue background, typical of the period, it depicts scenes from the Creation and the Last Judgment.
The chancel was not used for defence unlike that in Østerlars. The church font, from the late Romanesque period, is sculpted in Gotland limestone. The baptismal bowl from c. 1575 is from the south of Germany. Depicting a man's profile and the inscription Marcus Tullius Cicero, it was probably first used for affluent banquets. The stained-glass window in the apse, the work of Poul Høm, represents the resurrection with a seed developing into a plant.References:
Ängsö Castle was first named as "Engsev" in a royal charter by king Canute I of Sweden (r. 1167-1196), in which he stated that he had inherited the property after his father Eric IX of Sweden. Until 1272, it was owned by the Riseberga Abbey, and then taken over by Gregers Birgersson.
From 1475 until 1710, it was owned by the Sparre family. The current castle was built as a fortress by riksråd Bengt Fadersson Sparre in the 1480s. In 1522, Ängsö Castle was taken after a siege by king Gustav Vasa, since its owner, Fadersson's son Knut Bengtsson, sided with Christian II of Denmark. However, in 1538 it was given by the king to Bengtsson's daughter Hillevi Knutsdotter, who was married to Arvid Trolle.
In 1710, the castle was taken over by Carl Piper and Christina Piper. Ängsö Castle was owned by the Piper family from 1710 until 1971, and is now owned by the Westmanna foundation. The castle building itself was made into a museum in 1959 and was made a listed building in 1965. It is currently opened to visitors during the summers.
The castle is a cubical building in four stores made by stone and bricks. The lower parts is preserved from the middle ages. It was redecorated and expanded in the 1630s. The 4th storey as well as the roof is from the expansion of Carl Hårleman from 1740-41. It gained its current appearance in the 1740s.
