The village is located along the Odra River just before it joins the Pisuerga.
Historically it was head of the Castrojeriz judicial district, one of the fourteen that formed the municipality of Burgos, in the period between 1785 and 1833.
In the 1787 Floridablanca Census it fell under the jurisdiction of a lordship with its proprietor being the Marquesa de Camarasa, with an ordinary mayor.

It is believed to have been the former Castrum Sigerici.
The village is arranged like other villages along the Camino.
On this street-route there are several churches and notable buildings.
There is a castle, in ruins, which has a lot of history.
The village was established by Count Muño (or Nuño Nuñez), who defended the fort at the end of the ninth century against the Arabs.
Before that it had been a Celtiberian, Roman and Visigoth fortress.

In 974, Count García Fernández of Castile granted it a charter, the Charter of Castrojeriz, which is considered to be the 1st granted in Castile.

It is an example of Jacobean urbanism, with houses located around the street-route, which is the longest of all on the pilgrimage route.
As an important stage in the Camino de Santiago it had several hospitals along this street.

There is a cruise ship which sports a Cross of Tau (Tau) instead of the Latin cross perhaps as a reminder of the Order of the Antonians who had a monastery and hospital on the outskirts of the town, where they healed and tended to the sick afflicted by St. Anthony Fire, called also the holy fire, a disease now known to be caused by ingesting a fungal parasite on rye.
