They took Naarden easily. Its defence works were old and poorly maintained. In the 17th century Naarden was a small fortified town overlooking a stretch of dry ground between the sea and the marshes of the river Vecht (the fortifications dated from the 1570s). After Louis XIV of France invaded the Netherlands in 1672 the fortifications were updated to modern standards. Most of the fortifications that exist today date from this period. The fortifications can be separated into two parts: the part facing the sea and the part facing the land.
During the 19th century the fortifications were updated, resulting in the construction of many new bomb shelters and other army-related buildings like barracks. At the end of the 19th century the increased fire power and range of the artillery made the defences at Naarden useless.
As a consequence of the new strategies used in warfare the emphasis of the fortifications went from the inner to the outer circuit - the covered way. In the 1890s a lot of bomb shelters were built here, most of which still exist. This gives a nice visible illustration of the progression in fortification.
After the First World War the need for Naarden as a fortress was over. The army left and it was turned into a monument and preserved just in time to prevent it from being demolished. You can walk around and inside Naarden freely - the covered way makes an excellent walking path to discover the fortifications.
One of the bastions holds a museum about the fortress, which gives a lot of information about the town's history. The museum also gives access to all the tunnels and casemates, making it a must in exploring the fortress.
The landward fortifications consist of arrow-headed bastions'connected by curtain walls, of which the lower sections were made of bricks. The flanks have two levels; the top level is on the top of the bastion and the lower part is just a few metres above the water. The lower part of the flank, which can be reached through a tunnel from the street behind the bastion gives access to 5 casemates'in the faces of the bastions and a powder magazine. From the lower flank a tunnel leads to a small pier, from which the outworks could be supplied by boat. Beyond the last casemate lies the listening tunnel; a long tunnel along the face of the bastion where guards were able to hear the enemy approaching on the water through holes in the roof.
The large bastion holds the arsenal (now a furniture showroom) as well as a sluice gate. This sluice was used to protect the harbour and to enable ships to come into the town from the sea. Two batardeaux'were built across the ditch to connect the sea dam with the town walls. Around the whole town there was a covered way'with a second ditch in front of it. The town had two gates, of which both the originals have been demolished. The Amsterdam gate doesn’t exist anymore and the current Utrecht gate dates from the 19th century. In the 20th century a third entrance into the town was made.References:
Derbent is the southernmost city in Russia, occupying the narrow gateway between the Caspian Sea and the Caucasus Mountains connecting the Eurasian steppes to the north and the Iranian Plateau to the south. Derbent claims to be the oldest city in Russia with historical documentation dating to the 8th century BCE. Due to its strategic location, over the course of history, the city changed ownership many times, particularly among the Persian, Arab, Mongol, Timurid, Shirvan and Iranian kingdoms.
Derbent has archaeological structures over 5,000 years old. As a result of this geographic peculiarity, the city developed between two walls, stretching from the mountains to the sea. These fortifications were continuously employed for a millennium and a half, longer than any other extant fortress in the world.
A traditionally and historically Iranian city, the first intensive settlement in the Derbent area dates from the 8th century BC. The site was intermittently controlled by the Persian monarchs, starting from the 6th century BC. Until the 4th century AD, it was part of Caucasian Albania which was a satrap of the Achaemenid Persian Empire. In the 5th century Derbent functioned as a border fortress and the seat of Sassanid Persians. Because of its strategic position on the northern branch of the Silk Route, the fortress was contested by the Khazars in the course of the Khazar-Arab Wars. In 654, Derbent was captured by the Arabs.
The Sassanid fortress does not exist any more, as the famous Derbent fortress as it stands today was built from the 12th century onward. Derbent became a strong military outpost and harbour of the Sassanid empire. During the 5th and 6th centuries, Derbent also became an important center for spreading the Christian faith in the Caucasus.
The site continued to be of great strategic importance until the 19th century. Today the fortifications consist of two parallel defence walls and Naryn-Kala Citadel. The walls are 3.6km long, stretching from the sea up to the mountains. They were built from stone and had 73 defence towers. 9 out of the 14 original gates remain.
In Naryn-Kala Citadel most of the old buildings, including a palace and a church, are now in ruins. It also holds baths and one of the oldest mosques in the former USSR.
In 2003, UNESCO included the old part of Derbent with traditional buildings in the World Heritage List.
