In this case it helps to know, first, that the card was mailed in 1974, with two stamps and clear postmark.  Then — and again with thanks to Wikipedia — we can tell you this about the hotel:  “The Grand Chateau, also known as  Chateau Tongariro, (was) a hotel and resort complex on the slopes of Mount Ruapehu, within the boundaries of Tongariro National Park, New Zealand’s oldest national park.  The building was completed in 1929 and, despite extensive refurbishment, still retains much of the style of the pre-Depression era and is listed by Heritage New Zealand as a Category 1 historic place.  Chateau Tongariro Hotel closed permanently on 5 February 2023, largely because the building has significant seismic risks.”  It’s worth seeing that Wikipedia entry in full.  Grade: 1
