Where is the iconic location of the Cinque Terre ?

Are you talking about Manarola?

Yes

Five villages are arranged from west to east: Monterosso is the largest and also the flattest, with the most hotels and a beach; Vernazza is the village in the picture with the most internal bays, but to see this angle, you must climb up to a very high mountain peak; Corniglia is the only one of the five villages that the station is far away, and you must climb a zigzag steep slope to get to the village; Manarola and Riomaggiore are the two villages farthest to the east, and the hiking trail between them is the love path, but it is now closed. It's hard to say which village is the most beautiful, and it's hard to say which building is iconic. In my opinion, it needs to be combined with light effects, time, and angle, and it takes some physical effort and time.
