Osservanza is a small holding with a lot on it. In the survey of about 1820, the brothers Ermenegildo and Antonio Tamanti di Filandro held about 15 hectares here, with a chapel, a house, a threshing floor, vines and olives, and a chestnut grove.
The Tamanti parcels
In section F′, Osservanza, the brothers’ parcels are 6, 7, 11, 126, 137, 151–154, 158 and 169–170, twelve numbers scattered across the section rather than one compact block. (See the Tavole indicative, Tomo II p. 142, p. 143, p. 150, p. 151, p. 152 and p. 153.) The entries record a chapel and a house with a threshing floor, fields planted with vines and olives, and a chestnut grove.
The brothers’ two arable parcels in countryside section A, numbers 93 and 103 (owner entry; original on CASTORE), bring their holding across the two sections to fourteen parcels and about 17.5 hectares.

The research so far has not linked the chapel to a named or surviving building. Doing so would need the historic map overlaid on today’s landscape.
Santi neighbours
Osservanza is where Maria Tamanti’s husband appears in the survey. Clemente Santi di Luigi, the pharmacist who married Maria in 1819, held Osservanza parcels 205–206 and 209–211, with a house and threshing floor and about 4 hectares of vines and olives (owner entry; original on CASTORE). His mother, Petronilla Canali ne’ Santi, held parcels 229–231, and a separate Luigi Santi di Clemente held parcels 121, 188, 192–193 and 267. None of these Santi parcels was Tamanti land, and Maria is not named as an owner. Her marriage in 1819 does not show that any of this land came from her dowry. That question needs her marriage settlement. The Santi holdings are covered in the Biondi-Santi connection.
