The imperial elections were held in the Wahlkapelle, a chapel on the south side of the choir (Hochchor) built for this purpose in 1425 (See the Plan to the right) and the anointing and crowning of the emperors-elect as King of the Romans took place before the central altar–believed to enshrine part of the head of St. Bartholomew – in the crossing of the church, at the entrance to the choir (See the Plan to the right).
The Wahlkapelle chapel on the south side of the choir (Hochchor) was specifically built in 1425 for the imperial elections (Refer to the accompanying plan), and it was here that the anointing and crowning of the emperors-elect as King of the Romans occurred, prior to the central altar, which is said to house part of St. Bartholomew's skull.
