Christmas dinner plans were scrapped for about 100 people yesterday after a fire destroyed the manor house headquarters of West Midlands Safari Park.
The blaze, at the 250-year-old Spring Grove House, in Bewdley, started at about 10pm on Christmas Eve, with only the kitchen escaping the devastation.
The two-storey building housed the administrative offices of the safari park, where about 50 members of staff worked, and also its conference and banqueting suite.
A spokesman for West Midlands Safari Park said about 100 people had booked to have their Christmas dinner there, and weddings and other events had been planned for almost every day in the calendar.
Computer systems, files, records and office equipment were all destroyed in the blaze.
Only the kitchen, in the south wing, was saved by up to 50 firefighters battling to confine it.
"It is devastating for us," said spokesman Bob Lawrence. "It was our home really.
"A lot of people worked up there. I've been based in those offices for 35 years and we will have to get hold of people and try and restore things to normal."
Safari park staff managed to find other restaurants nearby for those who had booked to have their Christmas lunch there, and Mr Lee said they would work with people who had future functions planned there to secure other venues.
Firefighters battled for five hours to bring the blaze under control and, after consultation with rangers, they used water from the hippo pool when the mains proved inadequate.
At 2pm yesterday three fire engines were still at Spring Grove House - the old manor seat of the park - damping down.
The cause of the fire, which was discovered by security guards, is still unknown.
The house was yesterday unsafe for fire investigators to enter because of structural damage to the walls.
Spring Grove House is listed on the West Midlands Safari Park website as a perfect venue for banquets, dinners, parties and wed-ding receptions and is licensed for civil ceremonies.
