Thousands of Taylor Swift fans have got free seats to her concerts in Munich on a grassy hill near the concert venue.

The Swifties packed the Olympic Hill, or Olympiaberg, one of the highest elevations in the southern German city, for the second straight day Sunday. That gave them a high perch for watching the singer's sold-out concert in the nearby Olympic Stadium.

On Saturday, they braved the heat, which reached 31 Celsius (88 Fahrenheit) and claimed their spots hours before the concert began.

Police estimated that about 25,000 gathered on the hill on Saturday, according to the dpa news agency.

On Sunday, fans returned, once again packing the grassy hill with so many people that from a distance the scene looked like an anthill.

Rather than discourage the free viewings, the concert organiser handed out water and emergency blankets to those waiting to protect themselves from the sun, dpa reported.

Sunday's concert is Swift's last in Germany as part of her "Eras" tour. She heads next to the Polish capital, Warsaw, for three concerts this coming week, from Thursday through Saturday.
