The earliest references about the church date from 1316. The church was wooden at that time. During difficult periods of wars in the mid-15th century, during the Thirty Years' War, and Swedish invasions in 1643, it was burnt several times, but subsequently always renovated and rebuilt so that the faithful could gather again and celebrate the liturgy. Only after the destructive turmoil had subsided, a stone church was built in 1649. It was without foundation, unconsecrated, and subsidiary to Nábzí. It had neither its own parish priest, nor presbytery. Not until the 18th century, when Albrecht Maxmilian Des Fours succeeded to the Hrubý Rohozec demesne, did Brod receive its own presbytery and a priest with a permanent residence.
Under the patronage of Albrecht's son, Karl Josef, Count Des Fours, a bell tower was built next to the church because of an increasingly enlarging parish.
The Latin inscription above the main entrance was carved at that time. It reads “AeDes ConseCrata eXtat altissimo” a consecrated building rises towards heights. A relief double crest of Des Fours with a Corinthian pillar was placed above the portal.
The interior of the church is decorated with a painting of the Holy Family in a boat at sea on the ceiling of the presbytery. In 1932 and 1933, a modern altar was acquired and consecrated; it was made of red Slivenec marble and glass, and decorated with precious stones from Kozákov. The altar was designed by the architect Klenka and made by the professors and students from the local school of glassmaking. Above the tabernacle, there is a gilded statue of the patron saint of the church, St. James, by the sculptor Pešan. A painting with the motif of the decapitation of St. James painted according to the original by the distinguished artist Fuhrichoriginally located in the navewas unfortunately destroyed in the fire of the church in 1990.
Also completely destroyed, there used to be a Baroque altar in the corner of the nave, composed to a central glazed-in cabinet, in which a 15th century Gothic statue of the Pieta (the Virgin Mary holding the body of Jesus Christ after his death) was placed. The Pieta used to be the most precious monument of art in Železný Brod. A plaster copy has taken its place in the present. The pulpit located in the northern corner of the nave dates from 1761. In front of the pulpit, there is a pewter baptismal font from 1761. The paintings of the Stations of the Cross are from 1828. The parish church was preferred to the decanal church by Štěpán Cardinal Trochta, the bishop of Litoměřice, in 1970.
The surrounding wall was probably built at the same time as the church in the early 1760s, and the staircase was added. Two Baroque statues adorn the lower part of the staircase St. Anne on the left, and the Virgin Mary of Karlov on the right. In the upper part, there is a statue of St. John of Nepomuk. All the statues date from the second half of the 18th century. Until 1885, there was a cemetery on the premises of the church; it was later moved to its present location in Horecká Street. The bell tower (probably by Johann Georg Volkert) dates from 1761 according to the records; it is located on the edge of the church hill, southeast of the church, behind the walls of the former cemetery.
The largest of the original three bells, probably from the 15th century, is located inside the bell tower. The brick octagonal charnel house stands behind the church. It has pyramidal roof timbers covered with shingles. Originally, bones from unearthed graves were stored there; later it served as a depository.The late-Baroque presbytery, located north of the church, is possibly the first brick house in the town, also probably built by Volkert. In 1775 rebel farmers from Hrubá Horka smashed the ground floor windows so bars were attached to them. Behind the church, not far from the sacristy, there is a carved sandstone cross.
