 Kaunas cathedral stood out among similar military churches by its size (it was designed to fit 2,000 worshipers) and its unusual architecture - employing triple Corinthian columns in an otherwise typical "neo-Byzantine" (Romanesque) five-dome design.In total the exterior has 266 large and small columns and pilasters.This eclectic spin-off of mainstream "Byzantine" architecture (the so-called "Roman Byzantine" style) was hailed by contemporary architectural journalists, but never gained popularity.
