Final answer:
The passage recounts the Geats building a memorial tower for Beowulf, interring his ashes and the dragon's treasure within it, and the warriors honoring his legacy.
Step-by-step explanation:
The passage provided describes the Geats constructing a tower as per Beowulf's request, a strong and tall structure, notable from a great distance. The construction took ten days, with Beowulf's remains entombed within the edifice, and the treasures from the dragon's hoard—rings, necklaces, and ancient hammered armor—were buried in the sand, now rendered useless to mankind. Furthermore, twelve of the Geats' bravest warriors circled the tower on horseback, expressing their grief and celebrating their king's heroic deeds and reputation.
