  Rencontres de Blois

The picturesque old French town of Blois, famous for its XIV-XVIIth century chateau, is about 170 km (100 miles) from Paris in the beautiful region of the «Châteaux de la Loire».


1. Welcome and registration

Participants are expected to arrive on Sunday afternoon, May 31st. Registration at the conference office in the Château de Blois will start at about 15:00. A welcome cocktail will be offered to the participants and their families at 19:00. It will be followed by dinner at the Château.

2. Conference schedule

The conference will start on June 1st at 9:00 and will end at about 16:00 on June 5th.

The conference room will be located at the Château Royal de Blois itself.

The conference organisers hope and trust that participants WILL stay for the entire conference. That is the spirit in which this meeting is organised, in order to maximise the opportunities for scientific exchange. We regret, but the conference expenses cannot be reduced for partial attendance.

3. Conference facilities

a video projector connected to a dedicated computer will be available for presentations. It is advisable to come with a backup copy of your slides, on a USB key.

4. Registration

If you wish to participate in the conference, you should register as soon as possible using the on-line registration form which is on this web site.

The deadline for registration and hotel reservation is April 30th, 2015.

Nevertheless, it is advisable to reserve your hotel accommodation before April 15, 2015, since hotel rooms in Blois are limited in certain categories.

The registration fee for participants will amount to 370 Euros and Accompanying persons will be charged 150 Euros.

The meal package will amount to 300 Euros; this is independent of the registration fee.

The registration fee covers the conference banquet and the programmed conference social activities, i.e. travel to and tours of the Chateaux at Chenonceau, the Clos Lucé (the last residence of Leonardo da Vinci) and of course a guided tour of the Blois Chateau itself . In the case of participants, it also covers a copy of the conference proceedings.

Payment of the registration fee can be made as follows :

5. Meals (other than the conference banquet, which is covered by the registration fee)

In order to enhance the interaction and exchange between participants, all participants are requested to have lunch and dinner together. The conference has arranged with a caterer to serve lunch and dinner in the Château Royal de Blois.

For participants, the package cost for 5 days will be 300 euros and should be paid to the caterer upon arrival at the conference site; since this is a specially negotiated "package deal" for the conference, it cannot be reduced for partial attendance

For accompanying persons, there are two possibilities only (in either case, payment should be made to the caterer upon arrival at the conference site):

6. Accommodation

Hotel accommodation will be available in 3 categories :

one star (*), two stars (**) and three stars (***), all rooms having either a shower or a bath.

Participants are asked to arrange their accommodation themselves, in order to reduce the workload on the conference secretary. A certain number of hotels have agreed to hold rooms for the conference until April 15, 2015; the list, together with a link to an interactive map, can be found by clicking on, the hotel list link in the left hand column.

Only if for some reason you are unable to do this, should you indicate on the registration form that you would like the conference secretary to do this for you, indicating your requirements. In any case, if you prefer to stay in a three star hotel, you must make the reservation yourself, since those hotels require a credit card number to guarantee payment.

7. Social program

Various social activities are planned during the conference for participants, their families and guests : this will include tours of the Châteaux of Blois , and Chenonceau, the Clos Lucé (last home of Leonardo da Vinci) and a "Son et Lumiere" show at the Château de Blois (please bring your own headset for the audio guide). An additional program for the accompanying persons (cost not included in the above) will be organized in collaboration with the tourist office of Blois.

8. Travel

The most convenient way to reach Blois is to arrive in Paris and take a train (SNCF) from the Austerlitz railway station to Blois. There are frequent trains from Paris to Blois; the following schedule (just a few particularly convenient trains are indicated) is, for the time being, only indicative, being based on last year's schedule.
