人だけではなくて、建物や壁が微かに持っている魂魄も感じられます。

It's not just people — I can also sense the faint soul-essence that buildings and walls carry.

Literal

People [only-だけ][is-not-ではなくて], buildings [and-や] walls [subject-が] faintly have-[continuous-ている] soul-spirit [also-も] can-feel-[potential-られる][polite-ます].

A spiritual/paranormal statement. 魂魄 (konpaku) is a Chinese-origin literary word for 'soul, spirit' — more formal than 魂 alone. In Chinese thought, 魂 is the heavenly/yang soul and 魄 the earthly/yin soul, and together they form the complete animate essence. や is the non-exhaustive listing particle. 感じられる is the potential form of 感じる ('can sense, can feel'). ~だけではなく 'not only X.'
