Royal Chapel of St Katherine-upon-the-Hoe

The fortifications of Plymouth in Devon are extensive due to its natural harbour, its commanding position on the Western Approaches and its role as the United Kingdom's largest naval base. The first medieval defences were built to defend Sutton Harbour on the eastern side of Plymouth Sound at the mouth of the River Plym, but by the 18th century, naval activity had begun to shift westward to Devonport at the mouth of the River Tamar. During the Victorian era, advances in military technology led to a huge programme of fortification encompassing the whole of Plymouth Sound together with the overland approaches. Many of these works remained in military use well into the 20th century.

The Royal Citadel in Plymouth, Devon, England, was built in the late 1660s to the design of Sir Bernard de Gomme. It is at the eastern end of Plymouth Hoe overlooking Plymouth Sound, and encompasses the site of the earlier fort that had been built in the time of Sir Francis Drake. The citadel site is a Scheduled Monument and many of the buildings within are Grade II Listed.

The Prince Christian Victor Memorial is a war memorial on The Hoe in Plymouth. It was erected in 1902 to commemorate the death of Prince Christian Victor of Schleswig-Holstein, the eldest son of Queen Victoria's third daughter Princess Helena. He died of typhoid fever during the Second Boer War. It became a Grade II listed building in 1975. The memorial was designed by the architect Frederick William Marks, with three bronze panels made by the sculptor Onslow Whiting and one by Emil Fuchs. It comprises a tall obelisk of pink granite, about 12 m (39 ft) high, in several sections, the third from the bottom decorated with a palmette motif, the next fluted, and the last flaring out to the base. The obelisk stands on a square green granite plinth with plaques, on a lighter grey granite base of two steps. An inscription on the south face records that its foundation stone was laid by Lady Butler on 4 August 1902, and (now almost illegible) that the completed memorial was unveiled on 8 August 1903 by Lady Audrey Buller, wife of General Redvers Buller. Each side of the plinth has an arched recess with a bronze panel. The front panel (south) by Fuchs shows two angels lifting a soldier "towards another world" with an inscribed dedication of the memorial to Prince Christian Victor: "IN MEMORY OF / CHRISTIAN VICTOR PRINCE OF SCHLESWIG-HOLSTEIN / CAPTAIN & BREVET MAJOR, THE KING'S ROYAL RIFLE CORPS / DIED AT PRETORIA OCTOBER 29TH 1900, / ELDEST SON OF PRINCE AND PRINCESS CHRITIAN OF SCHLESWIG-HOLSTEIN / GRANDSON OF VICTORIA, QUEEN OF GREAT BRITAIN & IRELAND / EMPRESS OF INDIA". The other three sides have panels by Whiting which show, on the east and west sides, battles from the Boer War, including one (east) showing an attack by the Devonshire Regiment at Wagon Hill during the Siege of Ladysmith, and the other (west) showing the Somerset Light Infantry and the Gloucestershire Regiment in action; and the rear (north) has a long inscription, recording that the memorial was erected by the South Africa diamond merchant Alfred Mosely "TO THE MEMORY OF / CHRISTIAN VICTOR. PRINCE OF / SCHLESWIG-HOLSTEIN, AND / TO THE OFFICERS, NON-COM-/ISSIONED OFFICERS & MEN / OF THE GLOUCESTERSHIRE, / SOMERSET & DEVONSHIRE / REGIMENTS WHO FELL DURING / THE BOER WAR, 1899-1902". A plaster modello for this main inscription panel is held by the National Army Museum. To the sides of each panel, the granite is inscribed with the names of Boer War battles, with some repetition. On the south side are "COLENSO / SPION KOP / VAALKRANTZE / MONTE CARISTO" and "PIETER'S HILL / LADYSMITH / LAINGS NEK / BELFAST"; to the east "PIETFONTEIN / DEFENCE OF / LADYSMITH / KIMBERLEY" AND "PAARDEBERG / DREIFONTEIN / KNEIS / POPLAR GROVE"; on the north side "WITTEBERGEN / JOHANNESBERG / DIAMOND HILL / BOTHAVILLE" and "RELIEF OF / LADYSMITH / TUGELA HEIGHTS / LOMBARD'sKOP "; and to the west "ELANDSLAACTE / WAGON HILL / LADYSMITH / BERGENDAL" and "COLENSO / SPION KOP / LAINGS NEK / TUGELA HEIGHTS". The memorial is set on a small square of grass delimited by low chains hanging between granite bollards, at the east end of Hoe Park below the north west bastion of the Royal Citadel.

The Barbican is the name given to the western and northern sides of Sutton Harbour, the original harbour of Plymouth in Devon, England. It was one of the few parts of the city to escape most of the destruction of The Blitz during the Second World War and the preceding era of slum clearance following the Public Health Act 1848. Two or three streets still retain some of the architecture of a historic fishing port. The Barbican has the largest concentration of cobbled streets in Britain and contains 100 listed buildings.
