Campen Lighthouse
Campen Lighthouse is an active lighthouse in the village of Campen, by the Ems estuary, northwest of Emden, in the East Frisia region, state of Lower Saxony, Germany. At a height of it is the fourteenth tallest "traditional lighthouse" in the world and the tallest in Germany. The structure consists of a free-standing lattice tower with the stair shaft inside. The lighthouse was built in 1889 and went in service on 1 October 1891. The lamp of Campen Lighthouse has a light intensity of 4.5 million candelas, the most powerful lighthouse lamp in Germany. Remarkably, the aperture of its flashing light to the left and right has an angle of only 0.3 degrees. The continuous light aperture is also quite small, less than 0.6 degrees. The machine building contains the oldest workable diesel engine in Germany. It was built in 1906 and has a power of 15 kilowatts.

Candela
The candela ( or ; symbol: cd) is the unit of luminous intensity in the International System of Units (SI). It measures luminous power per unit solid angle emitted by a light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function (a model of the sensitivity of the human eye to different wavelengths). A common wax candle emits light with a luminous intensity of roughly one candela. If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured. The word ''candela'' is Latin for ''candle''. The old name "candle" is still sometimes used, as in ''foot-candle'' and the modern definition of ''candlepower''.

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ems (river)
The Ems (german: Ems; nl, Eems) is a river in northwestern Germany. It runs through the states of North Rhine-Westphalia and Lower Saxony, and discharges into the Dollart Bay which is part of the Wadden Sea. Its total length is . The state border between the Lower Saxon area of East Friesland (Germany) and the province of Groningen (Netherlands), whose exact course was the subject of a border dispute between Germany and the Netherlands (settled in 2014), runs through the Ems estuary. Course The source of the river is in the southern Teutoburg Forest in North Rhine-Westphalia. In Lower Saxony, the brook becomes a comparatively large river. Here the swampy region of Emsland is named after the river. In Meppen the Ems is joined by its largest tributary, the Hase River. It then flows northwards, close to the Dutch border, into East Frisia. Near Emden, it flows into the Dollart bay (a national park) and then continues as a tidal river towards the Dutch city of Delfzijl. Bet ...

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as ...

Emden
Emden () is an independent city and seaport in Lower Saxony in the northwest of Germany, on the river Ems. It is the main city of the region of East Frisia and, in 2011, had a total population of 51,528. History The exact founding date of Emden is unknown, but it has existed at least since the 8th century. Older names for Emden are Setutanda, Amuthon, Embda, Emda, Embden and Embderland. Town privilege and the town's coat of arms, the ''Engelke up de Muer'' (The Little Angel on the Wall) was granted by Emperor Maximilian I in 1495. In the 16th century, Emden briefly became an important centre for the Protestant Reformation under the rule of Countess Anna von Oldenburg who was determined to find a religious "third way" between Lutheranism and Catholicism. In 1542 she invited the Polish noble John Laski (or ''Johannes a Lasco'') to become pastor of a Protestant church at Emden; and for 7 years he continued to spread the new religion around the area of East Frisia.

East Frisia
East Frisia or East Friesland (german: Ostfriesland; ; stq, Aastfräislound) is a historic region in the northwest of Lower Saxony, Germany. It is primarily located on the western half of the East Frisian peninsula, to the east of West Frisia and to the west of Landkreis Friesland. Administratively, East Frisia consists of the districts Aurich, Leer and Wittmund and the city of Emden. It has a population of approximately 469,000 people and an area of . There is a chain of islands off the coast, called the East Frisian Islands (''Ostfriesische Inseln''). From west to east, these islands are: Borkum, Juist, Norderney, Baltrum, Langeoog and Spiekeroog. History The geographical region of East Frisia was inhabited in Paleolithic times by reindeer hunters of the Hamburg culture. Later there were Mesolithic and Neolithic settlements of various cultures. The period after prehistory can only be reconstructed from archaeological evidence. Access to the early history of Ea ...

Lower Saxony
Lower Saxony (german: Niedersachsen ; nds, Neddersassen; stq, Läichsaksen) is a German state (') in northwestern Germany. It is the second-largest state by land area, with , and fourth-largest in population (8 million in 2021) among the 16 ' federated as the Federal Republic of Germany. In rural areas, Northern Low Saxon and Saterland Frisian are still spoken, albeit in declining numbers. Lower Saxony borders on (from north and clockwise) the North Sea, the states of Schleswig-Holstein, Hamburg, , Brandenburg, Saxony-Anhalt, Thuringia, Hesse and North Rhine-Westphalia, and the Netherlands. Furthermore, the state of Bremen forms two enclaves within Lower Saxony, one being the city of Bremen, the other its seaport, Bremerhaven (which is a semi-enclave, as it has a coastline). Lower Saxony thus borders more neighbours than any other single '. The state's largest cities are state capital Hanover, Braunschweig (Brunswick), Lüneburg, Osnabrück, Oldenburg, Hildesheim, ...

List Of Tallest Lighthouses In The World
This is a list of the tallest lighthouses, by tower height (as opposed to focal height, i.e. height of the lamp of a lighthouse from water level). The list includes only "traditional lighthouses", as defined by ''The Lighthouse Directory'', i.e. buildings built by navigation safety authorities primarily as an aid to navigation. As such, its information regarding construction, year, and notes is from the list of tallest lighthouses at ''The Lighthouse Directory''. Sources are given for all other information. Heights are from the United States Coast Guard Light List for the United States and from NGA List of Lights for the rest of the world, unless a better source exists. Where several lighthouses share the same height, they share the same position, and are all marked with "=".
