<span>The portal of St Anne on the right of the western facade was built in 1200 and is the earliest of the three portals to be built. The tympanum is actually dated to about 1150 and was once part of the earlier cathedral of St Stephen whose western facade was once 40 metres to the west of the present Cathedral.
hope this helped :)

I'll edit this post and answer your question.
The answer is true. Accidentals are a note or pitch that is not part of the key signature that you're playing in, and these notes are marked by using the sharp (♯), flat (♭), or natural (♮) signs. Accidentals change the note they accompany either by raising or lowering it by a semitone (or half step).
