The Spires of Boreth was a location on the planet Boreth.

Located on the Klingon holy world, it was described as being a beautiful sight to see which was both graceful and lovely. There was a poem associated with the Spires which indicated them as being spears to the stars:

"Standing like spears to the stars

The Spires of Boreth pierce the heavens

A glorious army of spirit

To be wielded at Kahless's return."

In 2378, B'Elanna Torres visited Boreth where she saw the Spires of Boreth from orbit. (VOY novel: Homecoming)
