The first phase of Coventry Cathedral's emergency restoration work is complete.
The repair work took on an urgency when a crack suddenly appeared in the west section of the 14th Century ruins in September 2011.
Christine Doyle, from the cathedral, said she was "thrilled" the repairs were complete, though more work was needed.
Fundraising is ongoing as restoration is also necessary on the ruin's north side and in the crypt.
Ms Doyle said: "It's been a good start but we've still got a lot to do as we've got to work our way around and underneath the ruins because there's the crypt to be sorted out as well.
"We'd love to open up the crypts to the pubic but we can't as water is coming through the floor and there's so much water around there."
The condition of the ruins is monitored regularly so cathedral executive director, Jane Woodward, said it was a shock when the crack "suddenly appeared".
She added: "You could see daylight through the crack".
More than £350,000 was spent on repairs to the cathedral ruins in 2010, which was expected to secure the building structurally until 2013.
In October 2011 the ruins were placed on the World Monuments Fund's Watch List, a catalogue of cultural heritage sites around the globe which are in danger.
