Shortly after the Romans founded Cologne in 50 AD, they built a wall around the city. The wall was first expanded in the tenth century, and again in 1106, but due to the continuing growth of the city a new, 7 meters high wall was built in the twelfth and thirteenth centuries.
The most important of the twelve gates that gave entrance to Cologne was the west gate, known as the Hahnentor. After their coronation in Aachen, German kings arrived in Cologne through this gate to revere the shrine of the Three Magi in the Cologne cathedral. The gate was built between 1235 and 1240 and was probably named after a citizen named Hageno, who owned the nearby land.
The Hahnentorburg has two semi-circular, crenellated towers. The city's coat of arms is depicted above the entrance. The tower was restored in 1890 by the city architect Josef Stubben; a memorial plaque commemorates the architect's construction of Neustadt (new city) between 1881 and 1898 outside the former city walls. The tower was severely damaged during the Second World War, but was later reconstructed.References:
Heraclea Lyncestis was an ancient Greek city in Macedon, ruled later by the Romans. It was founded by Philip II of Macedon in the middle of the 4th century BC. The city was named in honor of the mythological hero Heracles. The name Lynkestis originates from the name of the ancient kingdom, conquered by Philip, where the city was built.
Heraclea was a strategically important town during the Hellenistic period, as it was at the edge of Macedon"s border with Epirus to the west and Paeonia to the north, until the middle of the 2nd century BC, when the Romans conquered Macedon and destroyed its political power. The main Roman road in the area, Via Egnatia went through Heraclea, and Heraclea was an important stop. The prosperity of the city was maintained mainly due to this road.
The Roman emperor Hadrian built a theatre in the center of the town, on a hill, when many buildings in the Roman province of Macedonia were being restored. It began being used during the reign of Antoninus Pius. Inside the theatre there were three animal cages and in the western part a tunnel. The theatre went out of use during the late 4th century AD, when gladiator fights in the Roman Empire were banned, due to the spread of Christianity, the formulation of the Eastern Roman Empire, and the abandonment of, what was then perceived as, pagan rituals and entertainment.
In the early Byzantine period (4th to 6th centuries AD) Heraclea was an important episcopal centre. A small and a great basilica, the bishop"s residence, and a funerary basilica and the necropolis are some of the remains of this period. Three naves in the Great Basilica are covered with mosaics of very rich floral and figurative iconography; these well preserved mosaics are often regarded as fine examples of the early Christian art period.
The city was sacked by Ostrogoth/Visigoth forces, commanded by Theodoric the Great in 472 AD and again in 479 AD. It was restored in the late 5th and early 6th century. When an earthquake struck in 518 AD, the inhabitants of Heraclea gradually abandoned the city. Subsequently, at the eve of the 7th century, the Dragovites, a Slavic tribe pushed down from the north by the Avars, settled in the area. The last coin issue dates from ca. 585, which suggests that the city was finally captured by the Slavs. As result, in place of the deserted city theatre several huts were built.
The Episcopacy Residence was excavated between 1970 and 1975. The western part was discovered first and the southern side is near the town wall. The luxury rooms are located in the eastern part. The 2nd, 3rd and 4th rooms all have mosaic floors. Between the 3rd and 4th rooms there is a hole that led to the eastern entrance of the residence. The hole was purposefully created between the 4th and 6th century.
