Historic artefacts from one of the Pilbara's oldest towns are feared to have been damaged when cyclone Christine battered the region this week.
Cossack was one of the places hardest hit by wind gusts topping 170km/h and heavy rain when the cyclone hit the coast overnight on Monday.
The former pearling town was largely abandoned in the 1950s but its old courthouse was home to an extensive collection of pieces dating back to the 1800s.
Most of the collection, which included tablecloths, clothing, maps and other documents, was temporarily stored in boxes on the floor while the courthouse was being repainted.
Roebourne shire president Peter Long visited the courthouse yesterday to check the damage done by the severe tropical cyclone, after being alerted by locals.
"The boxes were on the floor and the window broke during the cyclone and obviously water got through the broken window," he said. "The bottoms of the boxes have been damaged.
"The window that broke was facing the west and we probably had the worst of the cyclone."
Mr Long said once council workers had cleaned up the water inside the courthouse, the boxes would be opened so the contents could be dried. "I don't expect there to be significant damage," he said. "It's a lovely old place, very historic and of great value to WA. We're very proud of it."
But two private landowners, who donated items from their family history to the museum, are upset the damage was allowed to happen.
Alan Wilson, whose great grandfather William Shakespeare Hall helped settle the area in the mid-19th century, said the boxes should have been moved before the cyclone hit.
"I'm concerned that the museum seems to have been missed out in the preparation for the cyclone," he said.
"There was plenty of advance warning but no one thought to check on the museum and what was happening to the artefacts."
Geoff Van Waardenberg's great-grandfather Christopher Thompson lived in Cossack in the late 1800s and drew a map of the area detailing dwellings and those who lived in them.
"I have great fears that the map is going to be lost over this," Mr Van Waardenberg said.
Cossack was the Pilbara's first port.
