I’ll translate it here for the benefit of other posters, as there’s lots of good info there. Left image:

• [top left] fortress
• [top centre] defence tower
• [top right] AN IBERIAN SETTLEMENT
• [immediately below the above] central street: the life of the settlement was organised around it. Most habitations were on its both sides.
• [bottom left] plaza: it was the meeting place of the inhabitants of the settlement
• [bottom] walls: they surrounded the settlement and were made of stone.

Right image:

• [top left] A CELTIC SETTLEMENT
• [top centre-right] public buildings: at the centre of the settlement, usually there were buildings intended for political and religious purposes.
• [top right] hut: round shaped. The walls were made of adobe and stores; the roof was made of branches and straw
• [almost bottom left] lifestock enclosure: some livestocks was stored inside the settlement.
• [bottom] walls: the settlements were surrounded by a circular wall made of stone.

Corrections welcome given that I don’t speak Catalan at all.
