Romanesque church located inside the Keep
The Keep Church
The Romanesque church located in the top area of the Giglio castello is still quite recognizable today, although in the course of the construction of the modern-age fortifications it was incorporated and refunctionalized.
Particularly noteworthy is the texture of the stone masonry in filarotto (square stone blocks worked on all surfaces arranged to form horizontal courses of regular height and bound with lime mortar), typical of the Romanesque period that we can place in the middle of the 12th century.
The Keep Church
Inside, the building has a barrel-vaulted hall.
Although there are no specific contemporary sources, locally the church is attributed to the Holy Trinity (Begnotti 1999, p. 126).
Of particular note is the presence of a round-arched doorway.
The church assumed a new role within the modern-age fortification, positioned as it was at the entrance to the new enclosure and facing an internal open space.
Together with the church in the village and the keep it can be considered part of a building program put in place as part of the strengthening of control over the Island.
The only two possible actors are the counts Aldobrandeschi and Pisa.
It seems that, given the scale of the works, the city is more likely.
