German photographer Nina Kloss shot this image of the Sphinx Observatory in Switzerland on an iPhone 13 Pro.
"At over 3000m, the observatory is a unique architectural design," the photographer said.
"It serves as a bridge between the terrestrial world and the celestial heavens.
"The observatory, which also features a hotel, offers an immersive experience, inviting its guests to study the wonders of the natural world in an otherwise remote and hard-to-access area."
The judges said the building and its steadfast presence has "inspired many to seek out the secrets of the universe".
"Perched amidst the Swiss Alps, the Sphinx Observatory stands as an awe-inspiring testament to human ingenuity, merging science and nature in perfect harmony since the 1930s," the judges said.
Belgium-based photographer Alain Schroeder took this striking image in Dhaka, Bangladesh on a Fuji Xpro 2.
"Bangladesh needs a lot of material to push forward its development, and that is why you can see a lot of brick factories in the country, where men, women and even children work in difficult and dangerous conditions," Schroeder said.
"The men are covered with dust transforming them into earth statues that endangers their health."
The judges said praised the "powerful photo".
"(It) is a reminder that for all the wonder of the built world there are far too many men, women and children who suffer appalling injuries and conditions in the process," the judges said.
"No protection is given to them as the race towards urbanisation speeds up, the simple brick maybe a cheap option but it comes with a high price."
Photographer Azim Khan Ronnie took this colourful aerial shot of the Nandgaon Temple on a DJI Mavic 2 Pro.
"Nandgaon is a historical town in the Mathura district of the Indian state of Uttar Pradesh," the photographer said.
"It is believed that Krishna in his childhood lived in Nandgaon with his family.
"It was named after Nand Baba, father of Krishna and features lots of famous temples related to the times of Krishna."
The judges remarked there is a sense that everything around the temple sprung up as a result of the building being there.
"This drone photograph captures a ripple like effect flowing throughout the town with many of the buildings and roads circling the temple,' the judges said.
"What is clear is that this temple is an important place for the local community and those who visit Nandgaon for celebration.
"This wonderful 19th century temple is a magnet for people and their beliefs."
Azim Khan Ronnie captured a special moment at the National Mosque of Bangladesh on a Huawei P60 Pro.
"Thousands of people come together to pray over several floors of one of the biggest mosques in the world," the photographer said.
"Those taking part in group prayers can be seen neatly lined-up as they stand, sit, kneel and bow during prayers.
"The National Mosque of Bangladesh can hold up to 40,000 people, including in the outside open space."
The judges praised the image, which captured the relationship between people and places of worship beautifully in the image.
"This is a sacred place that unites hearts and fosters a deep bond between the mosque and its people, celebrating the beauty of cultural diversity and the power of collective prayers," the judges said.
Photographer Hongyi Lou took this image of the Kaizhou window in the Sichuan Province of China on a Fujifilm.
"The covered bridge that crosses the entrance encourages people to establish a connection between the lotus pond and the hills, using the building as a window to more fully appreciate the surrounding nature," Lou said.
The judges said the subject of this image is "stunning" during the day and night.
"Its exciting architecture serves as a gateway to the surrounding scenery and as a signpost to the rest of the world," the judges said.
Farshid Ahmadpour captured this incredible scene in Isfahan, Iran on a Canon EOS 6D Mark II.
"This is the ceiling of the Qeysarieh Gate, part of the ceremonial site of the Safavid court and a 400-year-old national mansion protected by UNESCO," Ahmadpour said.
The judges said the grand bazaars in Iran often encompass stunning gateways to entice customers on their way to the myriad of merchants within.
"Located to the north of the square, the exquisite Qeysarieh gateway was finished around 1605," the judges said.
"This is a fantastic example of Persian architecture."
Bright blue cabins in Italy provided inspiration for photographer Alice Barbieri.
"In this photo the geometry of the cabins creates a series of images that multiply symmetrically," she said about the image shot on a Samsung S20 FE.
"The blue colour prevails, the roofs of the cabins blend with the sky and the sea to create a very pleasing composition."
Photographer Xuyang Lin shot this image in the Guangdong Province in China on a DJ Air 2S drone.
"Located in Shunde, when you view the building from above it looks like an ancient necklace and yet it is made of buildings connected in a series," Lin said.
The judges remarked the photographer captured a "certain romance" in the shot with "tone and perspective".
"Drone photography is giving us all a new perspective on the world around us, letting us see the design and construction in its raw form from above," the judges said.
Henning Larsen Architects was the inspiration behind photographer Ursula Reinke's image after the business emerged as the winner of a design competition in the city of Vejle in Denmark.
"Their idea was to create an organic and at the same time sculptural form: a wave," Reinke said.
"Above all, the natural conditions found in the immediate surroundings inspired the architects to create this unusual building shape."
The judges remarked it is not often a residential building gives away so much floorplan to create a visual impact.
"There is such movement in this unique looking building, and it makes you wonder what it's like to live inside it," the judges said.
"One thing is for sure, no one will forget where you live."
This image was shot with a Nikon D810.
