The answer is: High Priest's

Matt 26:58,69-72 - Called the palace in KJV. He might be able to see something of the trial from here.

When Peter found himself in the High Priest's courtyard, he was in a hotbed of tension and fear. This was after the Last Supper, and tensions were high. His thoughts must have been a swirl of disbelief and confusion. Imagine being unable to comprehend how your beloved teacher was suddenly in peril, all while you were trying to blend into the background.

In his attempt to remain inconspicuous, Peter made a grave mistake, denying his connection to Jesus not just once, but three times! This wasn’t just a response to an eager servant girl; it represented a vitally significant moment in the early Christian narrative. Six different Gospels tell this story, emphasizing its importance craving confrontation with one’s own doubts.

Did you know that the High Priest’s courtyard was part of what many believe to be the religious authority structure of the time? It performed religious duties, often seen as a bridge between the ordinary people and the divine activities they observed. If you think about it, Peter’s fall echoes throughout later themes of redemption. Despite his fear-driven denial, he would transform himself later into a bold leader of the early Church after Jesus’s resurrection - it’s like a beautiful redemption arc that shows growth amid struggle.

So interestingly, each little misstep along Peter's journey adds threads to the richer fabric of the story - both human and divine woven together. It shows that even amidst ultimate trials, growth still finds a way.
