PUERTO BANÚS
The marina and the streets immediately around it, at the western end of the Golden Mile, roughly six kilometres from Marbella town.
A working marina with residential blocks built up to its edge. Stock here is overwhelmingly apartments and penthouses rather than villas, which is why the price per square metre runs so far ahead of the surrounding areas: you are buying frontage, not land. The retail is the port itself, and Marina Banús and Gray D'Albion sit directly behind it.
Counted here with its sub-areas: Atalaya de Río Verde
The 3 that mark the edges
Counted from 26 distinct homes asking €3,000,000 or more, deduplicated across the agencies listing them, 1 of which are on the market with more than one firm at once. 8 of the 26 come from a source that dates its listings individually; the rest publish one timestamp for the whole catalogue, so their prices are current but their edit dates are not evidence. Every figure is the agency's own asking price, linked above.
Lots we have published here
Numbers from the linked sources, dated as marked. Asking is not getting, for what sellers actually achieve, the catalogue keeps receipts.
