Mussenden Temple
The domed cylindrical Mussenden Temple is modelled on the Temple of Vesta near Rome. The temple is on a cliff edge near Castlerock.
It was built in 1785 by the fourth Earl of Bristol and Anglican Bishop of Derry, Frederick Augustus Hervey, for his cousin Mrs Frideswide Mussenden who died before it was finished.
It has been maintained by the National Trust and it contains items from the Bishop's house Downhill Castle which was burnt down.
The Bishop used it as a library. He also used its as a vantage point for the horse races which he set his clergy to on Downhill Strand below, where they had to compete for the best parishes.
St Columb's Cathedral
Built, like the walls by London businessmen, in the Planter's Gothic style, it was used as a battery during the Siege.
The lead from its old spire was stripped to make bullets and cannon shot and the cannon shell catapulted into Derry City by the be-sieging army to which they attached their terms of surrender after the Mountjoy broke the boom is still on display in the entrance hall.
Other artefacts in the cathederal include two captured French flags, a 17th century bishop's throne and a window panel depicting St Columb's mission to Britain.
The Guildhalll
Derry's Guildhall acts as a venue for art, dance, music and drama throughout the year.
The Guildhall was originally built in 1890 but had to be rebuilt after a fire destroyed it. The Guildhall has a large clock tower and very interesting stained glass windows including a representation of Follingby's picture, The Relief of Derry.
