LAS VEGAS, N.M. — For some 50 years, La Castañeda was considered the queen of Las Vegas, N.M. — an architectural diamond that welcomed locals and visitors alike during the days when train travel reigned.

The high and mighty dined alongside the hoi polloi in the hotel’s restaurant and bar, enjoying the famous Harvey House hospitality. The hotel’s 40 rooms were invariably filled with politicians, celebrities, soldiers and travelers looking to stop for the night before moving on, be it northeast out of New Mexico or south toward Albuquerque and then points west.

“Las Vegas, New Mexico, is the great undiscovered town of the Southwest, with more remarkable history and architecture than Taos or Albuquerque,” said entrepreneur Allan Affeldt, who is restoring the long-shuttered hotel to its former glory. “And La Castañeda Hotel, where Teddy Roosevelt and his Rough Riders held their first reunion in 1899 around the corner from Doc Holliday’s saloon, is the crown jewel.”
