The Block, or The Blockhouse, was the oldest standing structure on Ord Mynock. It was originally the fortress for the Galactic Republic troops but after the planet was secured, it was turned into a detainment facility.

It was two stories tall, with a long and low profile. It had one entrance, protected by triple blast doors. The Freeport Security Force had significantly upgraded the building. The walls were blast-proof, and all ventilation and sewage pipes were less than a half-meter wide to prevent infiltration.

The facility was run by the Freeport Security Force, and the administrative offices were located right inside the door of The Block.
