COBLENZ (KOBLENZ)  , a city and fortress of Germany, capital of the Prussian Rhine Province, 57 M . S.E. from Cologne by rail, pleasantly situated on the left bank of the Rhine at its confluence with the Mosel, from which circumstance it derived its ancient name Confluentes, of which Coblenz is a corruption . Pop . (1885) 31,669; (1905) 53,902 . Its defensive works are extensive, and consist of strong modern forts crowning the hills encircling the town on the west, and of the citadel of Ehrenbreitstein (q.v.) on the opposite bank of the Rhine . The old city was triangular in shape, two sides being bounded by the Rhine and Mosel and the third by a line of fortifications . The last were razed in 189o, and the town was permitted to expand in this direction . Immediately outside the former walls lies the new central railway station, in which is effected a junction of the Cologne-Mainz railway with the strategical line Metz-Berlin . The Rhine is crossed by a bridge of boats 485 yds. long, by an iron bridge built for railway purposes in 1864, and, a mile above the town, by a beautiful bridge of two wide and lofty spans carrying the Berlin railway referred to . The Mosel is spanned by a Gothic freestone bridge of 14 arches, erected in 1344, and also by a railway bridge . The city, down to 189o, consisted of the Altstadt (old city) and the Neustadt (new city) or Klemenstadt . Of these, the Altstadt is closely built and has only a few fine streets and squares, while the Neustadt possesses numerous broad streets and a handsome frontage to the Rhine .

In the more ancient

part of Coblenz are several buildings which have an historical interest . Prominent among these, near the point of confluence of the rivers, is the church of St Castor, with four towers . The church was originally founded in 836 by Louis the Pious, but the present Romanesque building was completed in 1208, the Gothic vaulted roof dating from 1498 . In front of the church of St Castor stands a fountain, erected by the French in 1812, with an inscription to commemorate Napoleon's invasion of Russia . Not long after, the Russian troops occupied Coblenz; and St Priest, their commander, added in irony these words—" Vu et approuve par nous, Commandant Russe de la Ville de Coblence: Janvier ter, 1814." In this quarter of the town, too, is the Liebfrauenkirche, a fine church (nave 1250, choir 1404–1431) with lofty late Romanesque towers; the castle of the electors of Trier, erected in 1280, which now contains the municipal picture gallery; and the family house of the Metternichs, where Prince Metternich, the Austrian statesman, was born in 1773 . In the modern part of the town lies the palace (Residenzschloss), with one front looking towards the Rhine, the other into the Neustadt . It was built in 1778–1786 by Clement Wenceslaus the last elector of Trier, and contains among other curiosities some fine Gobelin tapestries . From it some pretty gardens and promenades (Kaiserin Augusta Anlagen) stretch along the bank of the Rhine, and in them is a memorial to the poet Max von Schenkendorf . A fine statue to the empress Augusta, whose favourite residence was Coblenz, stands in the Luisen-platz . But of all public memorials the most striking is the colossal equestrian statue of the emperor William I., erected by the Rhine provinces in 1897, standing on a lofty and massive pedestal, at the point where the Rhine and Mosel meet . Coblenz has also handsome law courts, government buildings, a theatre, a museum of antiquities, a conservatory of music, two high grade schools, a hospital and numerous charitable institutions . Coblenz is a principal seat of the Mosel and Rhenish wine trade, and also does a large business in the export of mineral waters .

Its manufactures include pianos,

paper, cardboard, machinery, boats and barges . It is an important transit centre for the Rhine railways and for the Rhine navigation . Coblenz (Confluentes, Covelenz, Cobelenz) was one of the military posts established by Drusus about 9 B.C . Later it was frequently the residence of the Frankish kings, and in 86o and 922 was the scene of ecclesiastical synods . At the former of these, held in the Liebfrauenkirche, took place the reconciliation of Louis the German with his half-brother Charles the Bald . In 1or8 the city, after receiving a charter, was given by the emperor Henry II. to the archbishop of Trier (Treves), and it remained in the possession of the archbishop-electors till the close of the 18th century . In 1249–1254 it was surrounded with new walls by Archbishop Arnold II . (of Isenburg); and it was partly to overawe the turbulent townsmen that successive arch-bishops built and strengthened the fortress of Ehrenbreitstein (q.v.) that dominates the city . As a member of the league of the Rhenish cities which took its rise in the 13th century, Coblenz attained to great prosperity; and it continued to advance till the disasters of the Thirty Years' War occasioned a rapid decline . After Philip Christopher, elector of Trier, had surrendered Ehrenbreitstein to the French the town received an imperial garrison (1632), which was soon, however, expelled by the Swedes . They in their turn handed the city over to the French, but the imperial forces succeeded in retaking it by storm (1636) . In 1688 it was besieged by the French under Marshal de BoufHers, but they only succeeded in bombarding the Altstadt into ruins, destroying among other buildings the old merchants' hall (Kaufhaus), which was restored in its present form in 1725 .

In 1786 the elector of Trier, Clement Wenceslaus of

Saxony, took up his residence in the town, and gave great assistance in its extension and improvement; a few years later it became, through the invitation of his minister, Ferdinand, Freiherr von Duminique, one of the principal rendezvous of the French emigres . This drew down upon the archbishop-elector the wrath of the French republicans; in 1794 Coblenz was taken by the Revolutionary army under Marceau (who fell during the siege), and, after the peace of Luneville, it was made the chief town of the Rhine and Mosel department (1798) . In 1814 it was occupied by the Russians, by the congress of Vienna it was assigned to Prussia, and in 1822 it was made the seat of government of the Rhine province .
