The town of Londa with its 1500 inhabitants is one of the smallest in the province of Florence but it boasts ancient origins dating to the Etruscan times and also visible traces of their passage, such as the Portico of the Etruscans. Moreover, Londa is also known for its lake, an artificial basin built with the river Rincine's waters.

Since the VI century B.C., Londa had been an Etruscan "pago" and some tombstones lead to suppose that a still unexplored necropolis might exist nearby. Some towns' toponyms such as Rata, Rincine, Vierle, Vicorati are thought to have Etruscan origins, too. After the Romans conquered the Mugello in the III century b.C., Londa was a land of passage of the Carthaginian army led by Hannibal who had crossed the Alps starting from Spain with the aim to march in Rome. The road that crosses Londa was the best link to Arezzo, where there the famous leader's presence is ascertained.
Around the year 1000, Londa became one of the Counts Guidi's estates. The counts built and developed the historical nucleus of the chief town, which was built at the confluence of the rivers Rincine and Moscia.
The origin of the name Londa is peculiar. Since it is set on an island, the town got the name of "L'Onda" that was also recalled in the town's emblem. This territory was scarcely important from a strategic and economic point of view and Florence bought it quite late in comparison to other nearby areas.
Since 1375, when it entered the Medicean dominion, Londa developed gradually since it was the only village saved from Cosimo I's reprisals against the ancient defeated feudatories.
In the XVI century, Londa was a Town Hall under the jurisdiction of the Vicariate of Pionte a Sieve, while other hamlets were under the jurisdiction of Poppi. In 1654, the town was put under the control of the Guadagni family. The reunification of the modern town took place in 1766 under the Grand Duke Pietro Leopoldo of Lorraine. With an edict he issued the citizens were authorized to take material from the ancient and decaying medieval castles to build farmhouses. If on one side this despoiled the territory of Londa of some important historical goods, on the other it enhanced the local agriculture.
The town underwent damages both after the earthquake of 1929 and after the bombardments of 1944 that caused the destruction of the bridge, of the municipal palace and of some houses in the old city centre. The two events certainly influenced the depopulation and the emigration of numerous inhabitants from the town.
