"Collège Félix", the only boys' secondary school in the principality. For girls, she began by fixing set curricula for convents that also operated as schools, then set up a body of "dames d'inspection" to verify that these curricula were being adhered to. Teaching of girls aged 5 to 8 was made compulsory, though the laws were not always well applied. On 2 July 1807, Élisa founded the "Institut Élisa" within the limits of a former convent for noble-born girls, to produce well-educated and cultivated future wives. On 29 July 1812, Élisa set up an establishment for young poor girls, the "Congregazione San Felice", though this did not long outlive Élisa's fall. As with Napoleon, Élisa set up city improvement works in her territories, mainly to expand the princely palaces. These works were hotly contested, especially in Lucca, where the expansion of the princely palaces necessitated the demolition of the Church of San Pietro in March 1807. She also razed an entire block in Lucca to build a piazza in the French style in front of her city residence (now the seat of the province and the prefecture). That block had included the Church of San Paolo with the venerated image of the Madonna dei miracoli and so its demolition seriously affected the city's medieval architecture and almost sparked a revolt. At Massa, she demolished a cathedral on 30 April 1807. The palace at Lucca was fully redecorated and the gardens improved, with the creation of a botanical garden with a menagerie and aviary in 1811. She also began road construction, notably the "route Friedland" to link Massa and Carrara, with work beginning on 15 August 1807 but becoming delayed and only completed in 1820. Lucca's status as a spa town was also bolstered by her improvement of the architecture and decor of the town's baths. She began construction of an aqueduct into Lucca in 1811, but this too was only completed after her fall. Grand Duchess of Tuscany On 21 March 1801, Lucien Bonaparte and the King of Spain signed the Third Treaty of San Ildefonso, which restored Louisiana to France and in exchange established the Kingdom of Etruria by dividing Tuscany. The new kingdom was initially put in the charge of the infante Maria Louisa and her husband, Louis of Etruria, but he soon proved to be a poor ruler and deceased soon after in 1803. Thus, on 29
