The design similarity/connection being drawn to the Pergamon altar might be a bit of a stretch but the whole door/'portal' thing going on w/ the Pope and RCC is certainly interesting and significant and can't deny has Lucifer written all over it

Pergamon's history includes being the place the pagan Baal worshipping priests of Babylon settled after getting kicked out by Darius. The title of their high priest being Pontifex Maximus which was bestowed on the Bishop of Rome after he ascended the throne of Roman state power around 538 AD becoming the real *first Pope* of the Roman Catholic Papal church that reestablished the Babylonian religio-state system fulfilling the Biblically prophesied formation of THE antichrist/beast power.
