The oldest archaeological ruts from the Romans
were found southwest of today`s Rapale. Used as an easy abandoned settlement, it was also privileged by the climate, high over the Ambra valley.
During the feudal period, the Ubertini
are said to be the first lords of Rapale. They also ruled over the other castles in Valdambra. More detailed information you may find here. As usual during this period, Rapale like all the other places in the
valley, were plundered, occupied and set under fire by the Senese allies in 1307. A short Italian text, which describes the military activities during one month in 1307, may give an idea about the uneasy times at this period. Later, the castle returned
under the control of the Ubertini. Florence Republic fully protected and acquired Rapale in the year 1404. But in 1431 again the Senese became master of Rapale, as they entered in Valdambra again in 1431
assisted by the troops of the Duke of Milan. Florence answered immediately. 1433 the flag of Florence was seen again over the castle of Rapale. Siena several times tried to conquer the castles of
Valdambra, but Rapale remained under the government of Florence. Finaly Florence defeated the rival Siena, so that Rapale carried on its existence as a small community with own status until 1770.
Afterwards it was annexed to the Comune of Bucine.
