Kanakakkunnu Palace
Today the palace and its sprawling grounds are the venue for many cultural meets and programmes. An all India Dance Festival (October to March) is organized by the Department of Tourism every year. During this period the classical Indian Dance performances are conducted every day. There are several tourists streaming from many foreign countries every year.

History
It is said to be built by Sree Moolam Thirunal.It has been later used by the travancore royal family to entertain its guests and serve non vegetarian food as the royal family was vegetarian. It is now protected by the tourism department the palace plays host to a lot of cultural meets and programs. The Indian National Trust for Art and Cultural Heritage (INTACH) has listed this place as a heritage monument.
Napier Museum
The Napier Museum is an art and natural history museum situated in Thiruvananthapuram (Trivandrum), the capital city of Kerala, India.

Features
The museum houses a rare collection of archaeological and historic artifacts, bronze idols, ancient ornaments, a temple chariot and ivory carvings. It also contains the Sree Chitra Art Gallery, which contains works from Raja Ravi Varma and Nicholas Roerich, as well as examples of Mughal and Tanjore art.
The Museum grounds also hold the famous Trivandrum Zoo, which is one of the oldest zoological gardens in India. This Zoo was established in 1857 and is spread over 55 acres (220,000 m2) of land.
Neyyar Dam
Neyyar dam is a gravity dam on the Neyyar River in Thiruvananthapuram district of Kerala, South India, located on the foot of the Western Ghats about 30 km from Thiruvananthapuram.It was established in 1958 and is a popular picnic spot. Lying against the southern low hills of the Western Ghats, Neyyar Dam has a scenic lake.

Marine aquarium
A marine aquarium is an aquarium that keeps marine plants and animals in a contained environment. Marine aquaria are further subdivided by hobbyists into fish only (FO), fish only with live rock (FOWLR), and reef aquaria. Fish only tanks often showcase large or aggressive marine fish species and generally rely on mechanical and chemical filtration. FOWLR and reef tanks use live rock, a material composed of coral skeletons harboring beneficial nitrogen waste metabolizing bacteria, as a means of more natural biological filtration.
Marine fishkeeping is different from its freshwater counterpart because of the fundamental differences in the constitution of saltwater and the resulting differences in the adaptation of its inhabitants. A stable marine aquarium requires more equipment than freshwater systems, and generally requires more stringent water quality monitoring.[1] The inhabitants of a marine aquarium are often difficult to acquire and are usually more expensive than freshwater aquarium inhabitants. However, the inhabitants of saltwater aquariums are usually much more spectacular than freshwater aquarium fish.

Marine fishkeeping history
he first saltwater tanks were Venetian glass jars where the Romans kept anemones outdoors, but these systems were very short lived.
In 1846, Anna Thynne maintained stony corals and seaweed for almost three years, and was credited as the creator of the first balanced marine aquarium in London.[3][4]
Personal saltwater fishkeeping began on a wider scale in the 1950s, starting with the basic rectangular glass aquariums (usually 20 gallon), still popular today. Bleached coral along with a substrate of coarse crushed coral were the norm. Algae, including beneficial types such as coralline algae, were viewed negatively and were generally removed. The clean, sterile tank was viewed as the healthiest.
During the early days of marine aquaria, saltwater was collected at local beaches. Natural saltwater contains many unwanted organisms and pollutants. Aquarium literature of the time suggests that the most commonly kept marine fish were the percula clownfish, sergeant major damselfish, small, brackish-water puffer fish and scats, jeweled blennies, and blue damsels. Aquariums were equipped with large air compressors, and were heavily aerated and filtered (primarily with under gravel filters, a norm for some time).
An ever-growing number of hobbyists experiencing the inconvenience of gathering natural sea water and the concurrent development of analytical chemistry techniques led to research into the chemical composition of sea water. Synthetic salt mixes were developed to replicate the chemical environment of the tropical ocean, including trace elements and salts. This advance made marine fishkeeping popular in areas without access to clean sea water.
Air driven, counter-current protein skimmers and reliable submersible electric heaters were invented in Germany. Various advances in filtration included trickle and hang-on filters, both allowing a more natural equilibrium in the aquarium environment. The advancement of fluorescent lighting technologies to provide higher output, along with metal halide lighting, enabled the first reef tanks, making it possible to keep corals and other invertebrates without natural sunlight.
More efficient chemical testing allowed aquarists to understand the chemical properties of aquariums. By the 1980s, a biologically-based understanding of how to maintain an artificial ocean environment brought more successful and widespread marine fishkeeping.
