The church of San Juan del Hospital is located within a block of houses situated between the streets of La Mar, Sant Cristòfol, Miracle, and Trinquet de Cavallers. Two entrances on the last two streets allow access to a courtyard or passage called "del Calvari," which features an 18th-century Valencian ceramic Via Crucis. At the entrance of Trinquet de Cavallers street, there is an atrium with red crosses from the 13th century, a symbol of the Order of Malta. The north side of this courtyard preserves a series of arcades that likely belonged to the medieval cemetery; on the south side stands the church.

To the left of the courtyard, there is a bell tower from the first half of the 17th century, beneath which opens a Romanesque door with a plain round arch, crowned by an ancient shield of the Order of Saint John of Jerusalem. The study of this shield has allowed establishing that this door predates the door of the Palace or the Almoina of the Valencia See.

Also in the Romanesque tradition are the buttresses supporting the walls and bearing the weight of the vault, some arrow slits and corbels on the walls, and the mural paintings of the first chapel on the north side, unique in all of Valencia.
