Fagradalsfjall erupted

Fagradalsfjall is an active tuya volcano formed in the Last Glacial Period on the Reykjanes Peninsula, around 40 kilometres (25 mi) from Reykjavík, Iceland. Fagradalsfjall is also the name for the wider volcanic system covering an area 5 kilometres (3 mi) wide and 16 kilometres (10 mi) long between the Svartsengi and Krýsuvík systems. The highest summit in this area is Langhóll at 385 m. No volcanic eruption had occurred for 815 years on the Reykjanes Peninsula until 19 March 2021 when a fissure vent appeared in Geldingadalir to the south of Fagradalsfjall mountain. The 2021 eruption was effusive and continued emitting fresh lava sporadically until 18 September 2021.

Emley Moor transmitting station collapsed

Emley Moor has been a transmission site since the earliest days of commercial television in the UK. The present concrete tower is the third antenna support structure to have occupied the site. The first permanent transmitter built there was for ITV, covering much of the north of England. It had a 443 feet (135 m) lattice tower, which provided limited coverage. In 1964, in anticipation of colour PAL transmissions set to begin in 1966, the original 443-foot (135 m) lattice tower was replaced by a taller 1,265-foot (385.5 m) guyed mast. On 19 March 1969, a combination of strong winds and the weight of ice that had formed around the top of the mast and on the guy wires caused the structure to collapse.

1932
Sydney Harbour Bridge was opened

The Sydney Harbour Bridge is a steel through arch bridge in Sydney, spanning Sydney Harbour from the central business district (CBD) to the North Shore. The view of the bridge, the harbour, and the nearby Sydney Opera House is widely regarded as an iconic image of Sydney, and of Australia itself. Nicknamed "The Coathanger" because of its arch-based design, the bridge carries rail, vehicular, bicycle and pedestrian traffic. It is the eighth longest spanning-arch bridge in the world and the tallest steel arch bridge, measuring 134 m (440 ft) from top to water level. It was also the world's widest long-span bridge, at 48.8 m (160 ft) wide, until construction of the new Port Mann Bridge in Vancouver was completed in 2012.

Sagrada Família construction started

The Basílica i Temple Expiatori de la Sagrada Família, shortened as the Sagrada Família, is an under construction church in the Eixample district of Barcelona, Catalonia, Spain. It is the largest unfinished Catholic church in the world. Designed by architect Antoni Gaudí, his work on Sagrada Família is part of a UNESCO World Heritage Site. On 19 March 1882, construction of the Sagrada Família began under architect Francisco de Paula del Villar. In 1883, when Villar resigned, Gaudí took over as chief architect, transforming the project with his architectural and engineering style, combining Gothic and curvilinear Art Nouveau forms.
