While there was a royal palace in Locarno in 866 and a noble family with a castle in the 10th century, the oldest remaining parts of the Castello (part of the ring wall and residential tract and foundation of a tower) date to the late 12th or 13th century.
In 1164 Emperor Frederick Barbarossa granted Locarno the right to hold a market and for the first time mentioned the Capitanei di Locarno or noble families that administered the town and the Pieve or local church. While the Capitanei enjoyed the right of imperial immediacy, they did not always support the emperor. By around 1240 Locarno had become a stronghold of the Guelph faction which supported the pope against the emperor, possibly leading to the construction or expansion of the castle. In 1260 the Castello was attacked and destroyed by the pro-emperor Ghilbellines, leading Simon di Orelli, the most powerful member of the Capitanei to join the Ghilbellines and bring the town to the emperor's side until his death in 1290. The castle was rebuilt following the destruction of 1260.
During the 14th century Milan under the Visconti aggressively expanded into the valleys at the foot of the Alps. In 1342 Lucchino and Giovanni Visconti besieged and captured the castle from both the landward and lake sides. Many members of the Capitanei were captured. After accepting the Visconti as their new overlords, they were quickly released from captivity and restored to their former positions under a podestà appointed by Milan. The podestà became the only resident of the castle and some of the buildings were allowed to fall into ruin. However, under the Visconti the fortifications were strengthened and new defensive walls were built.
In 1439 the Visconti appointed Franchino Rusca as podestà in Locarno. Under the Rusca family, the castle was renovated, repaired and expanded. It was transformed into an ornate late medieval administrative castle. A little south of the old main tower, a palazzo was built with ornate halls, large chimneys, and an arcade leading to the courtyard. It was surrounded by a ring wall with machicolations and half-round towers which were topped with swallow-tail merlons. Today, part of the Rusca castle wall still remains on the south-west side of the castle compound. By the mid to late 15th century the Duke of Milan became concerned that the Rusca family might support the Old Swiss Confederacy against Milan. He appointed a castellan to manage the castle for him. The Rusca family remained at the castle in the palazzo, while the castellan lived in the old main tower, known as the Rocca. The various castellans often wrote letters to Milan asking for money to repair the old, uncomfortable tower and more soldiers to garrison it.
In 1495 Louis XII of France offered Locarno to the Swiss Confederacy in exchange for military help against Milan. Four years later he invaded Lombardy and quickly captured the castle and town of Locarno. However, he continually delayed and avoided handing the town over to the Swiss. In 1503, the Confederation invaded and conquered the Leventina valley and captured Locarno. However, the Treaty of Arona, in the same year, gave the fortifications at Bellinzona to the Confederation but returned the town to France. In 1507 the castle complex was expanded, for the last time, when the Rivellino, a triangular bastion, was added to the north side of the complex. In 2006 the historian Marino Viganò presented evidence that the Rivellino was designed, planned and constructed by Leonardo da Vinci, though no surviving documents prove this.
In 1512, during the War of the League of Cambrai, the Confederation again invaded the Alpine foothills including Locarno. They besieged the castle, but did not have the artillery needed to capture it. In 1513, negotiations after the decisive Swiss victory at the Battle of Novara gave temporary control over the castle to the Swiss. The 1516 peace treaty which ended the War of the League of Cambrai gave them permanent control over much of Ticino including Locarno.
The Swiss appointed a landvogt to administer Locarno for the Confederation from the castle. The expense of maintaining the large complex soon proved to be too much and in 1531 they decided to demolish much of the complex. By 1532, most of the walls were demolished, leaving only the palazzo. Three years later the fortifications at the harbor near the castle were also removed. Maintaining just the palazzo remained expensive and by 1762 the Landvogt Anton Schuhmacher reported that the roof was in such poor condition that it rained in every room. The castle remained the seat of the Swiss vogt until the 1798 French invasion of Switzerland and the creation of the Helvetic Republic. After the collapse of the Republic, the 1803 Act of Mediation created the new Canton of Ticino and transferred the castle to the new Canton. It was used as a cantonal administration building until 1921 when it transferred to the town of Locarno. Locarno repaired the castle and transformed it into a museum, the Museo civico e archeologico.References:
The Church of St Eustace was built between 1532-1632. St Eustace"s is considered a masterpiece of late Gothic architecture. The church’s reputation was strong enough of the time for it to be chosen as the location for a young Louis XIV to receive communion. Mozart also chose the sanctuary as the location for his mother’s funeral. Among those baptised here as children were Richelieu, Jeanne-Antoinette Poisson, future Madame de Pompadour and Molière, who was also married here in the 17th century. The last rites for Anne of Austria, Turenne and Mirabeau were pronounced within its walls. Marie de Gournay is buried there.
The origins of Saint Eustache date back to 13th century. The church became a parish church in 1223, thanks to a man named Jean Alais who achieved this by taxing the baskets of fish sold nearby, as granted by King Philip Augustus. To thank such divine generosity, Alais constructed a chapel dedicated to Sainte-Agnès, a Roman martyr. The construction of the current church began in 1532, the work not being finally completed until 1637. The name of the church refers to Saint Eustace, a Roman general of the second century AD who was burned, along with his family, for converting to Christianity, and it is believed that it was the transfer of a relic of Saint Eustache from the Abbey to Saint-Denis to the Church of Saint Eustache which resulted in its naming. Jeanne Baptiste d"Albert de Luynes was baptised here.
According to tourist literature on-site, during the French Revolution the church, like most churches in Paris, was desecrated, looted, and used for a time as a barn. The church was restored after the Revolution had run its course and remains in use today. Several impressive paintings by Rubens remain in the church today. Each summer, organ concerts commemorate the premieres of Berlioz’s Te Deum and Liszt’s Christus here in 1886.
The church is an example of a Gothic structure clothed in Renaissance detail. The church is relatively short in length at 105m, but its interior is 33.45m high to the vaulting. At the main façade, the left tower has been completed in Renaissance style, while the right tower remains a stump. The front and rear aspects provide a remarkable contrast between the comparatively sober classical front and the exuberant rear, which integrates Gothic forms and organization with Classical details. The L"écoute sculpture by Henri de Miller appears outside the church, to the south. A Keith Haring sculpture stands in a chapel of the church.
The Chapel of the Virgin was built in 1640 and restored from 1801 to 1804. It was inaugurated by Pius VII on the 22nd of December, 1804 when he came to Paris for the coronation of Napoleon. The apse chapel, with a ribbed cul-de-four vault, has at its centre a sculpture of the Virgin and Child of Jean-Baptiste Pigalle that the painter Thomas Couture highlighted by three large paintings.
With 8,000 pipes, the organ is reputed to be the largest pipe organ in France, surpassing the organs of Saint Sulpice and Notre Dame de Paris. The organ originally constructed by P.-A. Ducroquet was powerful enough for the premiere of Hector Berlioz" titanic Te Deum to be performed at St-Eustache in 1855.
