Maypole
（重定向自Maypole dance）
A maypole is a tall wooden pole erected as a part of various European folk festivals, around which a maypole dance often takes place.
The festivals may occur on May Day or Pentecost (Whitsun), although in some countries it is instead erected at Midsummer. In some cases the maypole is a permanent feature that is only utilised during the festival, although in other cases it is erected specifically for the purpose before being taken down again.
