THEY have worked through scorching heat and have been delayed by downpours of rain.

But the team revamping Oxford University’s Museum of Natural History is determined to finish most of the work by the new year.

The museum in Parks Road has been closed this year for the restoration of its 153-year-old leaky glass roof.

Rachel Parle, education officer, said: “Our beautiful canopy of 9,000 glass tiles has been admired since the museum first opened, but has caused 153 years of worry by letting the rain drip through into the interior.

“The determination to clean and seal the roof is the whole reason for this year’s closure.”

All the glass tiles are being removed, cleaned, refitted and sealed with mastic – plant resin – to keep the water out.
