The other buildings belonging to the Abbey were rebuilt in the seventeenth century. Inside, an interesting cloister still exists, with a Doric colonnade, shown on the opposite view. [Illustration: ENTRANCE THE ABBEY (RUE DE MEAUX)] After the Revolution the Abbey was turned into a hospital, then into barracks, and after that into spinning mills. In 1836 it became the College Saint-Vincent, counting among its pupils Marshal Canrobert and the poet José-Maria de Hérédia. Many inhabitants of Senlis took refuge in the Abbey cellars during the bombardment of September 2, 1914. St.-Vincent soon served as an annexe to the hospital, which was too small to hold all the wounded. In the photograph (_page 42_) we see the transport of the wounded being carried on by the Red Cross in September, 1914. This temporary hospital remained after the departure of the Germans, which explains the presence of the wounded seen in the foreground of the opposite view. =The Arena= (historical monument) _The gate at the entrance of the road leading from the Place de Creil to the Arena is sometimes locked. Apply to the Syndicat d'Initiative (Hôtel du Grand-Cerf) for the key._ [Illustration: ENTRANCE TO THE ARENA] The arena was discovered in 1864. It apparently goes back as far as the third century. The tiers encircle a track measuring 130 feet by 110 feet. Two large entrances, which were vaulted, lead into the arena at each extremity of the great axis. On the other axis are two little rooms, which were no doubt reserved for the gladiators. In the southern one, niches are hollowed in the wall: these probably served as cupboards. [Illustration: VIEW OF ARENA] FROM SENLIS TO MEAUX (65 km.) (See maps inserted between pages 80-81) via +Chamant+, +Montépilloy+, +Baron+, +Châalis+, +Ermenonville+. _Starting from the Compiègne Gate, we leave the town by the Route Nationale_ (N 17). _After having crossed the railway we turn to the right and follow_ N 32 _as far as the first road on the right bordered with trees, which leads to Chamant. A hundred yards this side of the village we enter a field enclosed by hedges, on the right of the road (2½ km.)._ In this field, which appears in the photograph (_p. 50_), the German troops were encamped. M. Odent, the Mayor of Senlis, and six other hostages were shot there (_pp. 49-50_). M. Odent's grave is near the wood which skirts the side of the field opposite the one which borders the road. Near the enclosing hedge is the grave of a German captain. _Go on to the village of =Chamant=, turn to the right, then to the left as far as the church, the steeple of which can be seen_. This church dates from the twelfth century, and was modified in the fourteenth and sixteenth. The Roman spire, shown below, is remarkable. In the interior, the capitals and vaulting decorated in many colours were restored at the expense of Napoléon the Third, as was also the tomb of Lucien Bonaparte's wife, which is to be found in the side chapel.
