The Church of the Acheiropoietos is a 5th-century Byzantine church in Thessaloniki.
The Acheiropoietos has been dated from its bricks and mosaics to ca. 450–470, making it perhaps the earliest of the city's surviving churches. It was modified in the 7th and again in the 14th–15th centuries. Known as the Panagia Theotokos in Byzantine times, it is dedicated to Mary. Its current name is first attested in 1320, presumably after a miraculous acheiropoietos ('not made by hands') icon of Panagia Hodegetria that was housed there. Byzantine sources also indicate that the cult of the city's patron saint, Saint Demetrius, was also practised there.
The building is a three-aisled basilica, some 28 m wide and 36.5 m long, with a wooden roof. Its eastern end is a semicircular vault, while on the western side a narthex, flanked by towers, and traces of an exonarthex survive. The three aisles are separated by columns, while the two side aisles have galleries above them. At the eastern end of the northern side aisle, a middle Byzantine chapel dedicated to St. Irene is attached. On the northwestern corner of the basilica, the stairway leading to the galleries survives. The current entrance is through a triple-arched opening (tribelon) that connects the narthex with the main nave, while on the southern side there is a monumental entranceway, which probably connected the church with the city's Byzantine-era thoroughfare. Another small adjoining building on the south side has been identified as the church's baptister The modern roof is lower than the original, where the section above the central nave was elevated to allow light in.
The surviving parts of the church's rich original interior decoration include particularly fine 5th-century Ionian capitals from a Constantinopolitan workshop, the green Thessalian marble columns of the tribelon, the original Proconnesian marble pavement of the central nave, and fragments of 5th-century decorative mosaics. Fine but damaged early 13th-century frescoes depicting the Forty Martyrs of Sebaste adorn the southern side. Underneath the north aisle's current pavement, three layers of floor mosaics from an earlier Roman-era bath have been uncovered.
After Ottoman conquest of the city in 1430, the Acheiropoietos was the first church to be converted into a mosque, by Sultan Murad II himself. Throughout the Ottoman period, it remained the city's principal mosque under the name Eski Camii ('Old Mosque'). An inscription by Murad survives in the northern colonnade, on the eighth column from the east.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
