German tourists are welcome from Monday back to Mallorca and the other islands of the Spanish Balearic Islands in the Mediterranean.
To be precise, 10,900 Germans can visit the local authorities.
It is a trial, and there are conditions attached to the stay.
Tourists do not have to be quarantined on arrival, as elsewhere in Spain, but must stay for at least five days.
The authorities want to know whether the safety provisions work at airports and hotels, for example.
The archipelago has chosen Germany because it is where most tourists come from who visit the islands.
