Taylor (Republican), each of whom claimed the election, Goebel was assassinated at Frankfort. (See also KENTUCKY.) Frankfort received a city charter in 1839. FRANKFORT-ON-MAIN (Ger. _Frankfurt am Main_), a city of Germany, in the Prussian province of Hesse-Nassau, principally on the right bank of the Main, 24 m. above its confluence with the Rhine at Mainz, and 16 m. N. from Darmstadt. Always a place of great trading importance, long the place of election for the German kings, and until 1866, together with Hamburg, Bremen and Luebeck, one of the four free cities of Germany, it still retains its position as one of the leading commercial centres of the German empire. Its situation in the broad and fertile valley of the Main, the northern horizon formed by the soft outlines of the Taunus range, is one of great natural beauty, the surrounding country being richly clad with orchard and forest. Frankfort is one of the most interesting, as it is also one of the wealthiest, of German cities. Apart from its commercial importance, its position, close to the fashionable watering-places of Homburg, Nauheim and Wiesbaden, has rendered it "cosmopolitan" in the best sense of the term. The various stages in the development of the city are clearly indicated in its general plan and the surviving names of many of its streets. The line of the original 12th century walls and moat is marked by the streets of which the names end in _-graben_, from the Hirschgraben on the W. to the Wollgraben on the E. The space enclosed by these and by the river on the S. is known as the "old town" (_Altstadt_). The so-called "new town" (_Neustadt_), added in 1333, extends to the _Anlagen_, the beautiful gardens and promenades laid out (1806-1812) on the site of the 17th century fortifications, of which they faithfully preserve the general ground plan. Of the medieval fortifications the picturesque Eschenheimer Tor, a round tower 155 ft. high, dating from 1400 to 1428, the Rententurm (1456) on the Main and the Kuhhirtenturm (_c._ 1490) in Sachsenhausen, are the sole remains. Since the demolition of the fortifications the city has greatly expanded. Sachsenhausen on the south bank of the river, formerly the seat of a commandery of the Teutonic Order (by treaty with Austria in 1842 all property and rights of the order in Frankfort territory were sold to the city, except the church and house), is now a quarter of the city. In other directions also the expansion has been rapid; the village of Bornheim was incorporated in Frankfort in 1877, the former Hessian town of Bockenheim in 1895, and the suburbs of Niederrad, Oberrad and Seckbach in 1900.
