Question: What Slovakian palace served as the location for the signing of a truce agreement between Napoleon and Holy Roman Emperor Francis II?
Context: Maria Amalia of Austria (26 February 1746 – 18 June 1804) was the Duchess of Parma, Piacenza and Guastalla by marriage.  Maria Amalia was a daughter of Empress Maria Theresa and Emperor Francis I.  She was thus younger sister to Joseph II, Holy Roman Emperor and older sister to Leopold II, Holy Roman Emperor, Maria Carolina, Queen of Naples and Marie Antoinette, Queen of France. The Primate's Palace (Slovak: "Primaciálny palác" ; Hungarian: "Prímási palota" ) is a neoclassical palace in the Old Town of Bratislava the capital of Slovakia.  It was built from 1778 to 1781 for Archbishop József Batthyány, after the design of architect Melchior Hefele.  In 1805, the Palace's Hall of Mirrors saw the signing of the fourth Peace of Pressburg, ending the War of the Third Coalition.  Today, it serves as the seat of Mayor of Bratislava. The Treaty of Lunéville was signed in the Treaty House of Lunéville on 9 February 1801.  The signatory parties were the French Republic and Holy Roman Emperor Francis II.  The latter was negotiating both on his own behalf as ruler of the hereditary domains of the Habsburg Monarchy and on behalf of other rulers who controlled territories in the Holy Roman Empire.  The signatories were Joseph Bonaparte and Count Ludwig von Cobenzl, the Austrian foreign minister. Gerasim Zelić (Serbian: Герасим Зелић ; 1752–1828) was a renowned Serbian Orthodox Church archimandrite, traveller and writer (a contemporary and compatriot of Dositej Obradović).  His chief work is "Žitije" (Lives), in three volumes.  They are memoirs of his travels throughout western Europe, Russia and Asia Minor from the latter half of the 18th century to the first decade of the 19th century and the famous personalities (Napoleon, Prince Eugène, Viceroy of Naples, Joseph II, Holy Roman Emperor, Leopold II, Holy Roman Emperor, Francis II, Holy Roman Emperor, Semyon Zorich, Catherine the Great, Alexander I of Russia, Stanisław August Poniatowski, Dositej Obradović) he met.  He had valuable original notes on people, religions, manners, customs, trade, etc. Karl Anselm, 4th Prince of Thurn and Taxis, full German name: "Karl Anselm Fürst von Thurn und Taxis" (2 June 1733, Frankfurt am Main, Free Imperial City of Frankfurt, Holy Roman Empire – 13 November 1805, Winzer bei Regensburg, Electorate of Bavaria, Holy Roman Empire) was the fourth Prince of Thurn and Taxis, Postmaster General of the Imperial Reichspost, and Head of the Princely House of Thurn and Taxis from 17 March 1773 until his death on 13 November 1805.  Karl Anselm served as "Prinzipalkommissar" at the Perpetual Imperial Diet in Regensburg for Joseph II, Holy Roman Emperor and Francis II, Holy Roman Emperor from 1773 to 1797. The fourth Peace of Pressburg (also known as the Treaty of Pressburg; German: "Preßburger Frieden" ; French: "Traité de Presbourg" ) was signed on 26 December 1805 between Napoleon and Holy Roman Emperor Francis II as a consequence of the French victories over the Austrians at Ulm (25 September – 20 October) and Austerlitz (2 December).  A truce was agreed on 4 December, and negotiations for the treaty began.  The treaty was signed in Pressburg (now Bratislava), at that time in Hungary, by Johann I Josef, Prince of Liechtenstein, and the Hungarian Count Ignaz Gyulai for Austria and Charles Maurice de Talleyrand for France. The Battle of Austerlitz (2 December 1805/11 Frimaire An XIV FRC), also known as the Battle of the Three Emperors, was one of the most important and decisive engagements of the Napoleonic Wars.  In what is widely regarded as the greatest ever victory achieved by Napoleon, the "Grande Armée" of France defeated a larger Russian and Austrian army led by Tsar Alexander I and Holy Roman Emperor Francis II.  The battle occurred near the town of Austerlitz in the Austrian Empire (modern-day Slavkov u Brna in the Czech Republic).  Austerlitz brought the War of the Third Coalition to a rapid end, with the Treaty of Pressburg signed by the Austrians later in the month.  The battle is often cited as a tactical masterpiece, in the same league as other historic engagements like Cannae or Arbela. Archduke Alexander Leopold of Austria (Alexander Leopold Johann Joseph; Hungarian: "Sándor Lipót" ; 14 August 1772 – 12 July 1795) was Palatine of Hungary, appointed during the reign of his father, Holy Roman Emperor Leopold II, and serving into the reign of his elder brother, Holy Roman Emperor Francis II. Nicolaus Thomas Host (December 6, 1761 in Fiume, now Rijeka – January 13, 1834 in Schönbrunn) was an Austrian botanist, and the personal physician of Holy Roman Emperor Francis II.  His botanical works include "Synopsis plantarum in Austria" and the four-volume "Austriacorum Icones et descriptions graminum"; he was also the first director of the botanical garden at the Belvedere palace.  The genus "Hosta" is named for him. Francis II (German: "Franz" ; 12 February 1768 – 2 March 1835) was the last Holy Roman Emperor, ruling from 1792 until 6 August 1806, when he dissolved the Holy Roman Empire of the German Nation after the decisive defeat at the hands of the First French Empire led by Napoleon at the Battle of Austerlitz.  In 1804, he had founded the Austrian Empire and became Francis I, the first Emperor of Austria, ruling from 1804 to 1835, so later he was named the one and only "Doppelkaiser" (double emperor) in history.
