Kronshtadt, also spelled Kronstadt, Cronstadt is a large fortress and St. Petersburg's main seaport. Traditionally, the seat of the Russian admiralty and the base of the Russian Baltic Fleet were located in Kronstadt guarding the approaches to Saint Petersburg. The historic centre of the city and its fortifications are part of the Saint Petersburg UNESCO World Heritage Site.
The fortress was founded by Peter the Great, who took the island of Kotlin from the Swedes in 1703. Pushkin's great-grandfather, Abram Petrovich Gannibal, oversaw its construction. The first fortifications were inaugurated on 18 May 1704. These fortifications, known as Kronstadt's Forts, were constructed very quickly. During the winter the Gulf of Finland freezes completely. Workers used thousands of frames made of oak logs filled with stones. These were carried by horses across the frozen sea, and placed in cuttings made in the ice. Thus, several new small islands were created, and forts were erected on them, closing all access to Saint-Petersburg by the sea. Only two narrow navigable channels remained, and the strongest forts guarded them.
Kronstadt was thoroughly refortified in the 19th century. The old three-decker forts, five in number, which formerly constituted the principal defences of the place, and defied the Anglo-French fleets during the Crimean War, became of secondary importance. From the plans of Eduard Totleben a new fort, Constantine, and four batteries were constructed (1856–1871) to defend the principal approach, and sevenbatteries to cover the shallower northern channel. All these fortifications were low and thickly-armored earthworks, powerfully armed with heavy Krupp guns in turrets. The town itself is surrounded with an enceinte.
During the Petrograd riots of the February revolution, the sailors of Petrograd joined the revolution and executed their officers, thus gaining a reputation as dedicated revolutionaries. During the civil war, the sailors participated on the red side, until 1921, when they rebelled against the Bolshevik rule.
Kronstadt and the supporting forts and minefields were the key to the protection of Petrograd from foreign forces. Despite this, the cruiser Oleg was torpedoed and sunk by a small motor boat after participating in a bombardment of Krasnaya Gorka fort that had revolted against the Bolsheviks. This was followed on 18 August 1919 by a raid of seven Royal Navy Coastal Motor Boats into the harbor of Kronstadt itself, damaging the Soviet battleships Petropavlovsk and Andrei Pervozvanny sinking a submarine supply ship, the Pamiat Azova.
In 1921, a group of navy officers and sailors, soldiers as well as their civilian supporters rebelled against the Bolshevik government in Soviet Kronstadt. The garrison had previously been a centre of major support for the Bolsheviks, and throughout the Civil War of 1917–1921, the navy of Kronstadt had been at the vanguard of the main Bolshevik attacks. Their demands included 'freedom of speech', a stop to the deportation to work camps, a change in Soviet war politics, and liberation of the soviets (workers' councils) from 'party control'. After brief negotiations, Leon Trotsky (then the Minister of War in the Soviet Government, and the leader of the Red Army) responded by sending the army to Kronstadt, along with the Cheka. The uprising was thus suppressed.
During World War II, Kronstadt was bombed several times by Nazi Germany's air force, the Luftwaffe. In August 1941 the Luftwaffe began bombing Kronstadt regularly.
Until 1998, Kronstadt was a closed city, from then on it became a touristic attraction with free access to its territory.References:
The Porta Nigra (Latin for black gate) is the largest Roman city gate north of the Alps. It is designated as part of the Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier UNESCO World Heritage Site. The name Porta Nigra originated in the Middle Ages due to the darkened colour of its stone; the original Roman name has not been preserved. Locals commonly refer to the Porta Nigra simply as Porta.
The Porta Nigra was built in grey sandstone between 186 and 200 AD. The original gate consisted of two four-storied towers, projecting as near semicircles on the outer side. A narrow courtyard separated the two gate openings on either side. For unknown reasons, however, the construction of the gate remained unfinished. For example, the stones at the northern (outer) side of the gate were never abraded, and the protruding stones would have made it impossible to install movable gates. Nonetheless, the gate was used for several centuries until the end of the Roman era in Trier.
In Roman times, the Porta Nigra was part of a system of four city gates, one of which stood at each side of the roughly rectangular Roman city. The Porta Nigra guarded the northern entry to the Roman city, while the Porta Alba (White Gate) was built in the east, the Porta Media (Middle Gate) in the south, and the Porta Inclyta (Famous Gate) in the west, next to the Roman bridge across the Moselle. The gates stood at the ends of the two main streets of the Roman Trier, one of which led north-south and the other east-west. Of these gates, only the Porta Nigra still exists today.
In the early Middle Ages the Roman city gates were no longer used for their original function and their stones were taken and reused for other buildings. Also iron and lead braces were broken out of the walls of the Porta Nigra for reuse. Traces of this destruction are still clearly visible on the north side of the gate.
After 1028, the Greek monk Simeon lived as a hermit in the ruins of the Porta Nigra. After his death (1035) and sanctification, the Simeonstift monastery was built next to the Porta Nigra to honor him. Saving it from further destruction, the Porta Nigra was transformed into a church: The inner court of the gate was roofed and intermediate ceilings were inserted. The two middle storeys of the former gate were converted into church naves: the upper storey being for the monks and the lower storey for the general public. The ground floor with the large gates was sealed, and a large outside staircase was constructed alongside the south side (the town side) of the gate, up to the lower storey of the church. A small staircase led further up to the upper storey. The church rooms were accessible through former windows of the western tower of the Porta Nigra that were enlarged to become entrance doors (still visible today). The top floor of the western tower was used as church tower, the eastern tower was leveled, and an apse added at its east side. An additional gate - the much smaller Simeon Gate - was built adjacent to the East side of the Porta Nigra and served as a city gate in medieval times.
In 1802 Napoleon Bonaparte dissolved the church in the Porta Nigra and the monastery beside it, along with the vast majority of Trier"s numerous churches and monasteries. On his visit to Trier in 1804, Napoleon ordered that the Porta Nigra be converted back to its Roman form. Only the apse was kept; but the eastern tower was not rebuilt to its original height. Local legend has it that Napoleon originally wanted to completely tear down the church, but locals convinced him that the church had actually been a Gaulish festival hall before being turned into a church. Another version of the story is that they told him about its Roman origins, persuading him to convert the gate back to its original form.
In 1986 the Porta Nigra was designated a World Heritage Site, along with other Roman monuments in Trier and its surroundings. The modern appearance of the Porta Nigra goes back almost unchanged to the reconstruction ordered by Napoleon. At the south side of the Porta Nigra, remains of Roman columns line the last 100 m of the street leading to the gate. Positioned where they had stood in Roman times, they give a slight impression of the aspect of the original Roman street that was lined with colonnades. The Porta Nigra, including the upper floors, is open to visitors.
