MÆSTRICHT, an ancient town of the Netherlands; is about four miles in circumference, and strongly fortified. The inhabitants, the number of whom is estimated at 18,000, are noted for making excellent fire arms. It contains an arsenal, a handsome town-house, and a good library. Both Papists and Protestants are allowed the free exercise of their religion, and the magistrates are composed of both. It is seated on the river Maese, which separates it from Wyck, and with which it communicates by a handsome bridge. Mæstricht revolted from the Spaniards in 1570, but was reduced in 1579. Louis XIV. became master of it in 1673; but it was restored to the states by the treaty of Nimeguen in 1678. It was again taken by the French in 1794, and remained in their possession till 1814. It now belongs to the kingdom of the Netherlands. E. Long. 5. 50. N. Lat. 50. 52.
