Duncan Arrives at the Castle
Ever walked into a trap without knowing it? That's exactly what's happening to King Duncan in this scene. He arrives at Macbeth's castle and can't stop raving about how lovely and welcoming it feels.
Banquo joins in with the praise, pointing out how even the birds love nesting here. He mentions the martlets (a type of swallow) that build their homes in every corner of the castle. These birds symbolise peace, love, and new beginnings - which is massively ironic given what's about to happen.
The dramatic irony here is absolutely brutal. Whilst Duncan and Banquo chat about how safe and pleasant everything seems, we know that Macbeth and Lady Macbeth are plotting the king's death. Shakespeare uses this contrast between appearance and reality to build serious tension.
Key Point: The religious imagery of "temple-haunting" birds makes Duncan's upcoming murder even more shocking - it's like a holy place being violated.
