what dose they opening description of the house in " The Fall of the House of Usher" Show?

The Narrator is describing his arrival on horseback at Roderick Usher's isolated abode one dreary evening. Immediately he feels an irrational fear upon viewing the huge, decrepit house. Among the mansion's singular features are windows which resemble eyes and a fissure in the stone zig-zagging its way through the facade. The house and surroundings are very gothic.
