・There are four Christian gravestones, protected by a cover building, at a site along National Route 251.
・These gravestones have no inscriptions, but two of them have a cross design, one of which is said to have played an important role in the discovery of Hidden Christian gravestones in Nagasaki Prefecture.
・It is said that there was a Seminário (seminary) nearby. There is a signpost for the “Historic site of the Seminário.”
