The poem is organized as an exercise in nocturnal contemplation where the landscape becomes an inner revelation. From the very first line, the poetic self positions themselves “from the bottom of the valley,” a symbolic place of retreat and humility, from which they observe an elevated and “sumptuous” form that stands out against the “black horizon.” This vertical movement — from the valley to the hill — structures the entire poem and reflects a yearning for elevation, which is not necessarily physical, but spiritual and existential.

The hill situated “to the west” carries a particular symbolism: the west is the place of the sunset, the transition between light and shadow, life and silence. In this liminal space, “imaginary walls” rise, suggesting that the fortress is not material, but built by perception and desire. The castle does not exist as stone, but as a vision — an architecture of the spirit silhouetted against the starry night.

The image of the “ghost fortress” and the “bulwark” reinforces this ambiguity between presence and absence. It is a place of defense, shelter, and resistance, but also ethereal and intangible. The poetic self recognizes themselves in this illusory space by stating “here I daydream”: wakefulness blends with dreaming, and objective reality dissolves into an experience of active imagination, where meaning is born more from intuition than from reason.

The sounds of the night, far from being peaceful, “blend with revolt.” The soundscape reveals an inner tension that finds a form of reorganization through nocturnal contemplation. It is in this contact with the night that “strength is back,” indicating that the vision of the castle — even if ghostly — acts as a catalyst for inner renewal and an impulse to “go my way.”

In the final part of the poem, nature definitively assumes the role of symbolic architecture. The oaks, described as “sleeping giants,” rise like living columns that draw the silhouette of the castle. The fortress ceases to be imaginary to merge with the landscape itself: a “castle of trees” that “lies beneath the moonlight.” This final image dissolves the separation between human construction and the natural world, suggesting a primordial harmony where strength, protection, and permanence come not from stone, but from life itself.

The poem, thus, proposes a redefinition of shelter and resistance. The castle is not a place to be conquered, but a vision to be recognized; it is not on the outside, but is born from the encounter between gaze, night, and landscape. By contemplating it, the poetic self finds direction and energy once again, affirming that imagination — when rooted in nature and silence — can become a true inner fortress.

From the bottom of the valley I glimpse
your sumptuous form
silhouetted against the black horizon
of this starry night

at the top of the hill
situated to the west
the imaginary
walls

a ghost fortress
a bulwark
a silhouette against the dark
here I daydream

the sounds of the night
blend with revolt
strength is back
to go my way

on the western slopes
in your direction
the oaks, sleeping giants
sumptuously draw your silhouette

the castle of trees lies beneath the moonlight
