Hey @fjorenca, thanks for your interest in the project. We are here to clarify the rules:

1. For 1001 Places to Remember, we had decided not to limit 3 photos. You can use as much photos as you like.
2. For 1001 Places to Remember, it is about places but not restricted to architectural buildings. It can be park, garden, beach and any place that you had been to.
3. There is no deadline for 1001 Places to Remember, but we do it in sessions. Each season will last for 2 weeks and we will close the session for the season's reward.

Hope this helps.

Cheers and Steem on!
