[7] The episcopal visitation of the diocesis of Vic from 1357–58 mentions the existence of two altars at the church of Sant Romà de Sau, dedicated to St Romanus and Virgin Mary.
The visitation of 1590, in seeking to enforce the sacrality of the churchyard in a period of shifting burial customs, also threatened to confiscate any laundry items hung out to dry in the cemetery.
[16] In mid-19th century, the geographical dictionary of Pascual Madoz cited the foggy climate and poor water quality in Sant Romà as responsible for the prevalence of intermittent fevers, gastrointestinal and rheumatic disorders among the villagers.
[5] The church and the oldest settlement of Sau were submerged when a dam was built on the Ter river in 1962 as part of the large-scale dam-building campaign of the Francisco Franco regime.
[11][1] The Catalan hiking pioneer Artur Osona i Formentí [ca] noted in 1882 a recent restoration to the church, which he judged to be in "fairly bad taste".
To the north rises a three-storey bell tower, whose second floor has bifora windows with plain capitals, a Lombard band and serrated mouldings at the top.
[11] Ignasi Ferrés i Iquino shot his Closed Exit (1955) in the old village of Sant Romà de Sau, and a number of historic house interiors appear in the film.
