Strandborough Castle is the central symbol of the novel, representing the feudal system in its entirety. It is a microcosm of the medieval world, where its physical structure directly mirrors its rigid social hierarchy. The imposing outer walls, moat, and gatehouse symbolize the power of the nobility and the stark division between the protected, privileged life within and the vulnerable, laborious life of the peasantry outside. Toby’s first impression of the Bailey emphasizes this scale and power, as he notes that his “father’s manor house, and his stables, would fit easily in this huge courtyard” (9). This observation immediately establishes the castle as the seat of immense authority. The castle advances the theme of Interdependence in Medieval Communities, concentrating power and resources while demanding service and fealty from all who live under its shadow.
Internally, the castle’s layout continues to enforce this hierarchical structure. The distinction between the Great Hall for feasting, the private Great Chamber for the lord and lady, the servants’ quarters, and the squalid conditions of the dungeons creates a physical map of social status. Toby’s journey is one of navigating this complex space as he learns his specific place and the duties that come with it. The castle is both a fortress offering protection and a prison of social convention. It demonstrates The Challenges of Medieval Life through its cold, drafty halls, while also providing the framework for Toby’s Coming of Age Through Duty. Ultimately, Strandborough Castle is a tangible symbol of the opportunities, limitations, and inequalities that defined the feudal system.
Platt uses the motif of hunting to develop the theme of Interdependence in Medieval Communities by exposing the fundamental injustices of the feudal system. For the aristocracy, the hunt is a highly ritualized and glorious sport, a demonstration of martial prowess and social dominance. The boar hunt is presented as an “exciting and dangerous” spectacle complete with horns, hounds, and a gathering of nobles (25). It is a communal expression of their supposed right to control the land and its resources for leisure. Toby’s desire to participate signifies his aspiration to join this elite world and master its codes of conduct. This form of hunting is a privilege, reinforcing the power structure that underpins the entire community.
In stark contrast, hunting for the commoner David is a secretive and dangerous act of survival. He is a poacher, and his taking of fish and rabbits from his lord’s land is a felony, a crime punishable by imprisonment or death. When he catches Toby watching him, his desperate command, “Thou hast not seen me, nor the fish!” (70), reveals the high stakes of his actions. For David, hunting is a necessary means of feeding his family, placing him in direct conflict with the lord’s absolute ownership of the manor’s resources. The duality of the hunting motif is central to the theme of Interdependence in Medieval Communities, illustrating how the same act can be either a noble pastime or a desperate crime, depending entirely on one’s position in the social hierarchy.
In Castle Diary, the motif of food and feasting illustrates The Challenges of Medieval Life. The type and quality of food consumed directly corresponds to an individual’s place in the castle’s rigid hierarchy. At the top are the elaborate banquets for nobility, featuring fantastical dishes like the cockatrice and decorative subtleties made of sugar, designed to display the host’s wealth and power. Meanwhile, the castle’s servants live on brown cheat bread and the monotonous, unappetizing salt fish served on Church-mandated fast days.
Platt’s exploration of the working class’s food insecurity gives the motif crucial development. Soon after his arrival at Strandborough, Toby notes that the Baron’s horses are “less hungry than the people who labour in the fields” (21). In part, the peasants struggle to feed themselves because they must harvest the lord’s crops just as their own fields become ready, a classist form of forced labor compensated with “miser’s pay.” The situation is worsened by England’s poaching laws, which declared that fish and wild game were the nobles’ property: “[A]ll of the fish in the river belong to the castle—not just those in the stewponds fed by the moat’s waters” (72). It’s an open secret that everyone in the village must resort to poaching to survive, an act that carries a death sentence for those convicted. Through the motif of food and feasting, Platt illustrates the daily challenges of medieval life and Toby’s growing awareness of his own privilege.
Toby’s archery practice serves as a motif of the theme of Coming of Age Through Duty. His progress with the bow and arrow mirrors his larger adaptation to the discipline and responsibilities required of a page destined for knighthood. Initially, Toby is clumsy and ineffective, equipped with a yew bow that is as tall as him and requires all his strength just to string. His frustration is palpable as he laments, “I am by far the poorest archer in the castle!” (37). This starting point establishes his journey as one of arduous, repetitive effort. Unlike the romanticized adventures he imagines, his training is a slow, frustrating process filled with failure, revealing that growth is achieved through persistent, unglamorous work rather than heroic deeds.
The archery butts become the training ground for more than just a martial skill; they are where Toby learns patience and resilience. When he finally improves, the Constable gives him a bigger, more difficult bow, reinforcing the lesson that mastery is a continuous challenge. His gradual improvement, marked by the fluke shooting of a sparrow and culminating in the gift of a new bow from his cousin Simon at the end of the diary, charts his development. Archery becomes a key element of Toby’s transformation, representing the discipline through which a boy is slowly and painstakingly shaped into a man capable of fulfilling his role in the noble world.
