Almost a year later, Gawain sets out to find the Green Chapel. On his journey, a directionless Gawain comes across a splendid castle where the Lord and Lady welcome him in to rest. The Lord of the Castle then offers him another contest: he will go hunting every day and he will give Gawain whatever he catches, on the condition that Gawain give him whatever he may gain during the day - Gawain accepts. What follows are three days of trials and temptation for Gawain, as he resists the Lady's increasingly explicit advances. The first two days she gives him a kiss, which Gawain gives to the Lord without divulging it's source in return for a deer and a hunted boar. On the third day, the Lady gives Gawain her sash, a girdle of green and gold silk. She assures him it is charmed and will protect him. Under the impression he is to face a certain death the following day, Gawain accepts the sash. The Lady and Gawain then exchange 3 kisses, which he bestows upon the Lord that night - keeping the sash hidden.

The two part on cordial terms, and Gawain returns to Camelot wearing the sash as symbol of his failure to keep his promise. The Knights of the Round Table absolve him of any blame, and decide they will each wear a green sash as a reminder to be honest and a reminder of Gawain’s great adventure.
