This building, to the invocation of Saint Bonaventure, a Franciscan convent was built under the initiative of Inácio Coelho, then vicar of Santa Cruz through funds he made available on 26 June 1641.

[1] Legend suggests that the church and convent were erected in order to fulfill a vow following the triumph of Portuguese forces over Spain during the Restoration War.

Beginning in the 20th century, the spaces were remodelled with the arrival of French who occupied part of the former-convent.

[1][3] In the late 20th century the Museum of Flores was installed in the building, in the former convent and cloister, while the ancillary structures were used by the French forces, until the local health center was established.

[1] Under resolution 18/2011/A, by act of the Regional Legislative Assembly of the Azores, several projects were established, that included: a future intervention and general renovation of the convent's paints, to be consulted by the property-owners, local parish administration and municipality of Santa Cruz; and the protection of the building owing to salt.
