ケムニッツ
語源
ケムニッツというめずらしい言葉は、近くの都市ツヴィッカウを流れて最終的にはエルベ川へそそぐツヴィカウア・ムルデ川（Zwickauer Mulde）を原住民のソルブ語で「石が多い（小川）」を意味するカミェニカ（Kamjenika）と呼ぶことから来ており、スラブ語系では「Kamen」は「石」で、「-ika」は女性形接尾詞である。
地勢・産業
エルツ山地の山麓辺りに位置し、これを越えるとチェコ領に達する。近隣の都市としては、約70キロ北西にライプツィヒ、30キロ南西にツヴィッカウがある。昔はドイツの楽器産業の中心地の一つで、ケムニッツァ・コンサーティーナやバンドネオンの発明とも縁の深い都市である。
歴史
12世紀、神聖ローマ皇帝ロタール3世の時代に建てられた。17世紀の三十年戦争で壊滅的な打撃を受けるが、その後復興した。19世紀以降、ドイツで産業革命が進展する中、工業都市として発展した。
第二次世界大戦後、1953年に東ドイツ政府が街を「カール＝マルクス＝シュタット」と改称し（「カール・マルクス都市」の意。ただしマルクスとケムニッツは直接関係がない）、カール＝マルクス＝シュタット県の県都となった。
1991年のドイツ再統一後、再び街の名称はケムニッツに戻された。
Urban renewal
Heavy destruction in World War II as well as post-war demolition to erect a truly socialist city centre left the city with a vast open space around its town hall where once a vibrant city heart had been. Because of massive investment in out-of-town shopping right after reunification, it was not until 1999 that major building activity was started in the centre. Comparable to de:Potsdamer Platz in Berlin, a whole new quarter of the city was constructed in recent years. New buildings include the Kaufhof en:department store by de:Helmut Jahn, Galerie Roter Turm with a façade by de:Hans Kollhoff and Peek & Cloppenburg clothing store by Ingenhofen and Partner.
