The lyrics tell the story of a man who, heartbroken after being rejected by a woman, dedicates himself to building a coral castle by the ocean to symbolize his love for her even though she may never return.

Meaning of "The Coral Castle" by Andrew Peterson

"The Coral Castle" explores the theme of unrequited love and the lengths people are willing to go to show their affection, even if it may never be reciprocated. The protagonist's determination to construct a symbolic gesture of his love, despite knowing that the woman may never see it, conveys a sense of devotion and selflessness. The castle serves as a physical manifestation of his emotions, a place where he can pour his heart and soul into, even if it ultimately remains unappreciated. The lyrics also touch on themes of sacrifice, resilience, and the understanding that love is not always about being loved in return, but about giving love to the fullest extent possible.
