By 1744, there were over 20 guns around Rosia Bay. Parson’s Lodge Battery was originally named the 9th Rosia Battery. The Parson’s Lodge name is first recorded in 1761 and reputedly refers to the dwelling of the parson of a church and hermitage named St. John the Green. At the height of its military importance, the battery had three 10-inch rifled muzzle-loading guns that guarded the approaches to Rosia Bay, which is the only natural harbour on The Rock. The guns were installed in 1884. These guns fired a 400-pound shell over two and a half miles.
Beneath the fort lies a narrow tunnel that at one time housed a one-metre gauge railway but which is now a road tunnel. The tunnel was one of two originally created to take large quantities of quarried stone from Camp Bay to the harbour’s South Mole when it was constructed in the 1880’s.
The battery was used during both World Wars and, in 1941 it had anti-aircraft and anti-tank guns as well as anti-aircraft searchlights installed.

In 1886 the local colonial authorities took over control of the Gibraltar Post Office and were able to issue their own stamps.Initially they overprinted Bermuda stamps but by December they had their own design.
However, they still sold Spanish stamps if required and between 1889 and 1898 the post office sold Gibraltar stamps valued in pesetas as this was the currency in circulation.
For the first fifty years, the Gibraltar Post Office had responsibility for the post office not only in Gibraltar but also for the British postal service in Morocco. This ended in 1907.

The foundation stone of St Andrew’s Church was laid in October 1853 and it opened for worship in May 1854.
At that time there was a large military presence on the Rock which included a substantial number of Scottish regiments, and the church was built by the efforts of Presbyterians who wished their own place of worship.

The ornate sandstone arch is set into the western façade of St. Jago’s Barracks at the southern end of Main Street, near Southport Gates. The arch is all that remains of the 16th century Spanish Hermitage of Our Lady of the Rosary (Spanish: Ermita de Nuestra Señora del Rosario). When the British converted the church into military stores, following the 1704 Capture of Gibraltar, the arch was kept and set into the façade of the larger barracks. It was once thought that the arch had been relocated to St. Jago’s Barracks from the Spanish: Iglesia de Nuestra Señora de la Cabeza (Church of Our Lady of the Head) in Villa Vieja (Old Town), within the precinct of the Moorish Castle, but it has since been proven that this was a misunderstanding and that the arch has always been in situ. Anton van den Wyngaerde’s 1567 detailed panoramic sketch of Gibraltar and its bay depicts the Hermitage of Our Lady of the Rosary at the southern limits of the city walls.

St. Jago’s Arch is defined as a Category B Listed Structure by the Government of Gibraltar under section 40 of the Gibraltar Heritage Trust Act of 1989. On 26 June 2013, Minister for Culture and Heritage Steven Linares MP, announced in his budget speech that a conservation project being carried out on the walls surrounding Southport Gates was being extended to include the restoration of St. Jago’s Arch. The project will include information and lighting of the monument.

The Southport Gate was formerly known as the Africa Gate, was the earliest of the trio of gates in the Charles V Wall. It was constructed by Italian engineer Giovanni Battista Calvi in 1552, under the reign of Charles V, Holy Roman Emperor. The Southport Gate bears the Royal Arms of Charles V, Holy Roman Emperor, as well as the coat of arms of Gibraltar. The gate was depicted in a 1627 map of Gibraltar by Spanish engineer Luis Bravo de Acuña. On the map now held by the British Museum, the Southport Gate and the adjacent Southport Ditch were labeled in Spanish as Puerta de África (English: Africa The Southport Ditch was a large trench which extended along the south side of Charles V Wall from the southwestern end of the South Bastion to the Flat Bastion at Prince Edward’s Gate.

The centre gate was constructed in 1883. The New Southport Gate was opened in the Charles V Wall to improve the flow of traffic. It was constructed during the reign of Queen Victoria and the term of Governor of Gibraltar General Sir John Miller Adye. It is ornamented with the coat of arms of the governor and that of Gibraltar, over which is the Royal Arms of Queen Victoria.

In the 19th century, the Southport Ditch was the site of an ordnance depot. In the 1880s, the South Bastion featured four new rifled muzzle loading guns. A magazine was built in Southport Ditch at that time to store the ammunition needed for the new guns. Today, one of the guns is mounted just inside the Southport Gates. By 1908, the magazine had been converted to use as a pumphouse.

Due to safety concerns, the then Gibraltar Governor, Lord Napier, shut down the theatre in 1882. It remained closed until 1891.
It was closed again in 1906 on the recommendation made by the Sanitary Commissioners that the performance licence should be withdrawn due to the filthy conditions.
The theatre was reconstructed in 1911 and reopened on 16th March 1914.
The Theatre Royal closed down for the final time in the mid 1980’s. The site was demolished and rejuvenated into a park and car park.
It had a capacity for around 1000 people and was a very popular entertainment venue.
