Having the qualities or characteristics of architecture; resembling or suggesting architectural design.
From 'architecture' plus the suffix '-esque' meaning 'in the style or manner of,' following the pattern of words like 'grotesque' and 'picturesque.'
The '-esque' suffix is basically French's gift to English for creating vague but evocative adjectives—'architecturesque' lets you describe something that *feels* like a building without it actually being one, like a dramatic outfit or a complex poem.
