Rue de Presbourg

Rue de Presbourg is a street in the 8th and 16th arrondissements of Paris. Since 1864 it has been named after Napoleon's 1805 diplomatic success at the Peace of Pressburg and, with the Rue de Tilsitt , it forms a circle around Place Charles-de-Gaulle....

. It was named after the Peace of Tilsit by a decree of 2 March 1864 (its spelling with the two final "t"s reflects old German spellings, which tended to double terminal consonants after short vowels).
