Note : In April 2016, the French Parlement passed a law allowing for punters to be fined up to 1 500 euros for paying a sex worker. It is very hard to tell how this is working in practice. From what we know so far, this law has mostly been used to remove 'local nuisance' and it is more likely that in general, the law is being ignored - because the police don't have the resources, for starters

Caen
The traditional area of place Saint Saveur appears to have been displaced to other areas, and French workers appear to have been largely displaced by foreign workers.
Africans formerly used to work from vans on cours Montalivet, but have now moved across the river to the Presqu'île de Caen (see image). According to the press, the workers feel safe here : "Nous avons de bons rapports avec la police et nous nous sentons en sécurité ici. Notre transfert s'est déroulé sans problème / We have a good rapport with the police and we feel secure here. Our transfer went through without problems".
Among the relevant streets are cours Caffarelli, quai de Normandie, rue Gaston Lamy.
Otherwise : Romanians on quai de Juillet and la promenade de Madame de Sévigné, the banks of the River Orne in general, or quai Hamelin.
Earlier they talked of 'torpedo-prostitutes' who lived in Paris and travelled up to Caen for the day. Apparently more women are now actually resident in the area.

Le Havre
THis seems to hanging on by the skin of its teeth. I need to research the situation further to be certain of the current state of affairs. Previously we had said :
Small and cheap but not of a particularly 'high standard' as such.
The center of gravity seems to have shifted recently. Previously it was concentrated on the rue LeSueur, adjacent to place Danton with one or two women on the rue Laperouse. With the demolition of the prison, the trade on the rue LaSueur appears to have finished, and recent renovations on rue Haudry appears to have done the same there. Thus leaving the rue Laperouse adjacent to the bar on the corner, with maybe just one 'frangine'.
It is also quite strange in not 'opening' until about 1400 and seeming to close down around 1800. There appears to be no activity during the night at all.
The view shows rue Laperouse where the 'center of activity' is close to the bar shown on the corner.

Rue / Boulevard St Denis

Despite the law of 2016, there now appear to be as many women here as before. And what's more, they usually make no attempt to speak with passers-by, just as though this new law had never been introduced.
On the boulevard St Denis, between rue St Denis and boulevard de Sebastopol, there are often a large number of (mainly) Chinese women. In the past, you might have been expected to take a metro ride out as far as Charonne or similar, but nowadays I think there is a good chance that they usually have a room within walking distance
Latest (but possibly inaccurate) news on this topic:
• Chinese Prostitutes of Strasbourg - St. Denis and Belleville
There are often one or two women further down rue St Denis between rue Réaumur and rue Turbigo (adjacent to the passage de Cerfs particularly).
In the past there were often a few older women right at the bottom of the rue St. Denis, around the rue des Lombards (but this might no longer be the case).
Many sex shops were formerly to be found in the 'middle' section of rue St Denis, i.e. south of the rue Reaumur. This trade has declined but now there is there the Love Hotel where 'exotic' rooms can be rented by the hour. (One sex shop does still exists at the top of the rue St. Denis, just down from the arch (incidentally, and there a few around the gare du Nord).
'Aux Belles Poules', rue Blondel 32, is a former brothel that has retained its interior (consequently it has had a preservation order slapped on it). It is due to be preserved and be opened for viewing.
• photograph from 1933, Brassai - Prostitute at angle of Rue de la Reynie and Rue Quincampoix From "Paris by Night", an area close to the bottom of the Rue St Denis
• report on the rue St Denis earlier (e.g. 60s)
• If you are interested in a short history of the rue St Denis area, go here. The porte St Denis and St Martin are reminders of the course of a former city wall of 1347, which is marked today by boulevards from the Bastille area and went from here down the current rue d'Aboukir.

Belleville
The 'unofficial' district around Belleville (an obvious Chinese district) appears to still exist, and the new law has probably given it a 'boost'. The number of women definitely seems to imply that the new law is not being applied.
The area lies adjacent to the Belleville metro station and north-west along Boulevard de la Villette and Rue Civiale. Sometimes outside the L'Espace Belleville de la CFDT (building of the CFDT), on the Boulevard de la Villette, and in the open space behind this building.

A town on the French border that appeears to have 'profited' from recent French laws on prostitution. In 2010, the Paradise was opened, which claims to be one of the biggest brothels in Europe, with.around 100 bedrooms. It lies on the main road in the south of La Jonquera
La Jonquera has announced fines of up to 3000 euros for prostitutes and their clients conducting their business in public.
(two other brothels under same ownership at at Melianta, near Banyoles (south of Figueres) and at Mont-Ras near Palafrugell on the Costa Brava).
