Grand Casemates Square

Gibraltar National Day, celebrated annually on 10 September, is the official national day of the British overseas territory of Gibraltar. The day commemorates Gibraltar's first sovereignty referendum of 1967, in which Gibraltarian voters were asked whether they wished to either pass under Spanish sovereignty, or remain under British sovereignty, with institutions of self-government.

Grand Battery is an artillery battery in the British Overseas Territory of Gibraltar. To the west of the grand battery was a very formidable flank which was considered to have been a "great annoyance to the besiegers." Known as the Muralla de San Bernando (English: St. Bernard's Wall) during Gibraltar's Spanish period, it was fully adapted to mount cannon facing the isthmus with the old Moorish archery towers being pulled down and replaced by bastions.This battery forms part of a series of batteries built on the Moorish and Spanish lines that zigzagged up the hill of the Moorish Castle to the Tower of Homage on the Rock of Gibraltar. Seven of these batteries were formed along the city's walls.

The North Bastion, formerly the Baluarte San Pablo (St. Paul's Bastion) was part of the fortifications of Gibraltar, in the north of the peninsula, protecting the town against attack from the mainland of Spain. The bastion was based on the older Giralda tower, built in 1309. The bastion, with a mole that extended into the Bay of Gibraltar to the west and a curtain wall stretching to the Rock of Gibraltar on its east, was a key element in the defenses of the peninsula. After the British took Gibraltar in 1704 they further strengthened these fortifications, flooding the land in front and turning the curtain wall into the Grand Battery. Today, the bastion is surrounded by reclaimed land to the west and north. Glacis Road runs along the base of the bastion's former glacis. Smith Dorrien Avenue separates the bastion from the curtain wall, which is still largely intact. The bastion is occupied by the Giralda Gardens and a pétanque club. The Government of Gibraltar has plans to rehabilitate the site as part of a plan to develop the old fortifications as tourist attractions.

Barcina Gate was a city gate in the British Overseas Territory of Gibraltar. It was located near the port and formed part of the walls, towers and one of three separate access gates which were later named Barcina by the Spanish. Henrique de Guzman was hanged on one of the turrets of the gate here.

Castle Batteries are a series of artillery batteries that are part of the Northern Defences of the British Overseas Territory of Gibraltar. The batteries descend from the Moorish Castle to end at the sixth and seven batteries which are known as Crutchett's Batteries. There are brick vaulted bombproof rooms (casemates) under Crutchets Battery. The batteries were part of the northern defences of Gibraltar. Armies can only attack Gibraltar without ships from the north and therefore this is heavily fortified around the only gate to Spain called Landport. Cornwell describes how this was defended by "several batteries, numerous batteries on the Glacis of Landport, by Crutchett's and the Grand Battery". He speculated that no army could withstand the grapeshot from 400 "pieces of heavy artillery".

The Landport (Spanish: Puerta de Tierra) is a gate into the territory of Gibraltar. It was originally the only entrance to the fortification from the land and so was heavily fortified and guarded.

The West Place of Arms is a place-of-arms in the British Overseas Territory of Gibraltar that was originally used as a troop assembly point. It is located in the gap between the North Bastion and its Counterguard, a structure built in 1804. The Counterguard provided defensive cover for the West Place of Arms, which was also fortified by a ditch into which a large caponier projected. In 1834 the Counterguard was recorded as being armed with thirteen 24-pdrs and two 9-pdrs. They were replaced by ten 32-pdrs and two 8-inch howitzers between 1859 and 1863. By 1885 there were three 32-pdr smoothbore guns, two 8-inch howitzers and four 64-pdr rifled muzzle loaders (RMLs). The other guns were gradually replaced by RMLs in the final years of the 19th century.

The Montagu Bastion is one of many bastions which were designed to protect Gibraltar. Montagu was joined to Orange Bastion by a curtain wall known as Montagu Curtain and this bastion was protected by the Montagu Counterguard.

Granada Gate was a city gate in the British Overseas Territory of Gibraltar. It was the main entry point by land to the old town of Gibraltar.

Couvreport Battery is an artillery battery in the British Overseas Territory of Gibraltar.

The Abudarham Synagogue (Ladino: Esnoga Abudarham) is an Orthodox Jewish congregation and synagogue, located at 19 Parliament Lane, in Gibraltar, a British overseas territory of the United Kingdom.

The third siege of Gibraltar was mounted between February–June 1333 by a Moorish army under the prince Abd al-Malik Abd al-Wahid of Morocco. The fortified town of Gibraltar had been held by Castile since 1309, when it had been seized from the Moorish Emirate of Granada. The attack on Gibraltar was ordered by the recently crowned Marinid ruler Abu al-Hasan Ali ibn Othman in response to an appeal by the Nasrid ruler Muhammed IV of Granada. The onset of the siege took the Castilians by surprise. The stocks of food in Gibraltar were heavily depleted at the time due to the thievery of the town's governor, Vasco Perez de Meira, who had looted the money that was meant to have been spent on food for the garrison and to pay for the upkeep of the castle and fortifications. After over four months of siege and bombardment by Moorish catapults, the garrison and townspeople were reduced to near-starvation and surrendered to Abd al-Malik.
