30 April 1948,
The first prisoners were taken to Martutene prison in Donostia. They had to empty Ondarreta prison, and although the new jail on the Urumea margin was not finished, the prisoners began to move. The first accesses to Martutene were 49 women. Ondarreta prison was abandoned until the City Hall auctioned the management of its waste.
The Franco authorities celebrated with all their greatness the act of laying the first stone.
Here are several photographs of the prison construction.
And finally, open a picture of the newly pulled civil guards.
