In Mont Louis there is nothing to be seen of particular interest. The church was built from designs of Vauban. On the terrace is the monument of General Dagobert, who died in 1794. It consists of a pile of granite surmounted by a bomb. Dagobert was, however, not a native of this place, but of Saint Lô, in Manche. He had been sub-lieutenant in the regiment of Touraine in the Seven Years’ War, and when the Revolution broke out he was sent as General of Division with the army of Italy, and met with some success. He was less fortunate when commanding an army in the Pyrénées Orientales; he met with defeat at Trouillas, and was relieved of his charge and arrested. But he succeeded in justifying himself, before the Committee of Public Safety, by showing that his failure was due to the jealousy and disobedience of the generals placed under his orders. He was re-established in his position and allowed to carry on the campaign according to a plan proposed by himself to the Convention. He reached Perpignan in March, 1794, but could not obtain from Dugommier more than a few battalions in place of the 12,000 infantry and 600 cavalry that had been ordered to be placed at his disposal. At the head of a small body of men he went to Puygcerda and invaded Catalonia, took the strong position of Monteska, and surrounded Urgel. On 10 April he entered that city, which redeemed itself from sack by paying a contribution of 10,000 francs. Then he attempted to besiege the citadel, but found it to be too strong to be taken, and he retreated on the morrow. He was conveyed ill to Puygcerda on 17 April, where he died. To the south-east of Mont Louis is Planès, where there is a curious church, some suppose of Moorish constructure, by others attributed to the tenth century, by others again set as late as the twelfth. It consists of an equilateral triangle, surmounted by a cupola, and each angle rounded off. That this curious monument should be of Moorish origin is most improbable. The Arabs in France destroyed much, but built nothing. The hermitage of Font-Romeu is a pilgrimage resort with a Calvary, situated at the height of 5330 feet, and commanding a wide panorama.
