All of Chopin's compositions include the piano. Most are for solo piano, though he also wrote two piano concertos, a few chamber pieces, and some songs to Polish lyrics. His keyboard style is highly individual and often technically demanding; his own performances were noted for their nuance and sensitivity. Chopin invented the concept of instrumental ballade. His major piano works also include mazurkas, waltzes, nocturnes, polonaises, études, impromptus, scherzos, preludes and sonatas, some published only after his death. Influences on his compositional style include Polish folk music, the classical tradition of J. S. Bach, Mozart and Schubert, the music of all of whom he admired, as well as the Paris salons where he was a frequent guest. His innovations in style, musical form, and harmony, and his association of music with nationalism, were influential throughout and after the late Romantic period.

"Alsatia", the Latin form of Alsace's name, has long ago entered the English language with the specialized meaning of "a lawless place" or "a place under no jurisdiction" - since Alsace was conceived by English people to be such. It was used into the 20th century as a term for a ramshackle marketplace, "protected by ancient custom and the independence of their patrons". As of 2007, the word is still in use among the English and Australian judiciaries with the meaning of a place where the law cannot reach: "In setting up the Serious Organised Crime Agency, the state has set out to create an Alsatia - a region of executive action free of judicial oversight," Lord Justice Sedley in UMBS v SOCA 2007.

During the Franco-Prussian War and the Siege of Strasbourg, the city was heavily bombarded by the Prussian army. The bombardment of the city was meant to break the morale of the people of Strasbourg. On 24 and 26 August 1870, the Museum of Fine Arts was destroyed by fire, as was the Municipal Library housed in the Gothic former Dominican church, with its unique collection of medieval manuscripts (most famously the Hortus deliciarum), rare Renaissance books, archeological finds and historical artifacts. The gothic cathedral was damaged as well as the medieval church of Temple Neuf, the theatre, the city hall, the court of justice and many houses. At the end of the siege 10,000 inhabitants were left without shelter; over 600 died, including 261 civilians, and 3200 were injured, including 1,100 civilians.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): To what era did the Museum of Fine Arts date?
Ah, so..
