The church dedicated to St. Christopher is located in the town of Assemini, near the parish church. It was made in the 17th century, during the Spanish rule in Sardinia, but there is no certain data regarding the foundation. The oldest documents consist of some ‘Acts of the Municipal Council,’ in which it is reported that as early as 1820 the present small church of St. Christopher was used as a ‘surgeon’s store,’ a place where Asseminians went for dental extractions and other minor medical procedures. In the gabled facade with culminating single-light round-arched bell gable, there is a wooden portal surmounted by a small window. The interior presents a simple single hall of rectangular shape with a wooden roof. Slightly elevated from the rest of the hall is the essential altar surmounted by a niche containing a statue dedicated to the saint for whom the church is named: St. Christopher.
