These drawings by Jeffrey Chew of 19th-century colonial fortifications, so called Martellos, are easily adapted to the peculiarities of Martian warfare, primarily by the addition of machine guns or pompoms that are supposed to engage airborne foes. After all, raids by High Martians are uncomfortably common at outlying garrisons that guard mountain passes or caravan routes.
On Venus, one would find these towers next to trading posts and ports.
Jet Propulsion Laboratory, one of NASA’s top research facilities, is currently investigating whether it is feasible to design a wind-powered clock-work rover for Venus, tentatively named Automaton Rover for Extreme Environments (AREE). The basic concept was conceived by Jonathan Sauder, a mechatronics engineer at JPL.
AREE is designed to function on Venus’s surface without electronics, because the searing (470°C) and crushing (92 bar) atmosphere destroys such components quickly. Fortunately, the planet’s forceful winds can power Savonius wind turbines that provide the required mechanical energy for ground propulsion and on-board devices, for example a mechanical computer. Ergo, AREE is a clock-tech design made of hi-tech materials able to survive in that hellish environment for months.
AREE communicates with a Venus orbiter by a contraption of radar-reflective panels that can be set at various angles. The orbiter broadcasts a radar signal that is reflected back from those panels; the received “image” is then decoded by the orbiter. This simple device is comparable to Morse code or 18th-century semaphore telegraphs. (Also, check the movie The Martian where a stranded astronaut devises a similar method to communicate with Earth.)
The eminent site XKCD has published this picture that compares the surface areas of notable rocky celestial bodies in our solar system. The four giant planets are excluded because they lack mappable surfaces. The arrangement would be laid out nicely on the type of Ringworld that Larry Niven proposed in some of his stories — link >>>

NASA is currently investigating what materials and devices could be used for future Venus landers. The planet’s hellish environment degrades even stainless steel quickly, so research probes have so far ceased to function within two hours after touchdown. The Glenn Extreme Environments Rig is a 14-ton testing chamber that recreates Venus’s toxic, corrosive, and hot surface conditions.
