The centre for UK PSYOPS and subversion - MI6... What else could it be?
There are certainly exceptions; but most of the best buildings in the history of the world were built by members of "craft-guilds" (such as masons) - and without "architects".
And, for sure, over the past century since Art Deco; architecture has had a powerfully malign influence.
The deliberate anti-beautiful impulse of the past century of architects is evident from the difference between the housing of recent domestic buildings - which are merely practical-without-beauty*, and those that were architect-designed with big budgets.
(*Or, at least, houses were mostly functional; until the allegedly "anti-Carbon" and "environmental" regulations began to inflict complex, expensive, dysfunctionality on all construction work.)
Whereas the large, "showcase", private and public buildings - those that employ high-status architectural corporations or individuals; are anti-aesthetic, anti-human, anti-God monstrosities.
Such that the purposive, actively-evil turn of our civilization is advertised explicitly, unambiguously, indeed shamelessly - more by its architecture than by almost anything else.
