Before the construction of "Big Taxiarchis" the villagers used to have as their main church that of Old Taxiarchis. You can go to this church by following the road which starts from the square. The dome with the icon and the suspended oil-lamp at the side road he will meet, the "proskynima" as it is named, leads to the old church of Taxiarches.
The village has numerous, mainly small, churches, which stand out from the village houses because of their low height and their roofs. The largest and most important of these is the New Taxiarchis church which was built in 1868 on the site of the castro’s old circular tower near the central square of the village, or the "livadi” (meadow) as the Mestousoi (villagers) call it. Locals and visitors alike gather in the square to enjoy food, coffee and pastries.
The New Church of Taxiarchis
The church is dedicated to Taxiarches - Archangels: Michael and Gabrielle. It is usually called "The Big Taxiarchis" by the villagers so that to be distinguished from the other church of Taxiarchis which is more ancient and smaller in size. That one is named "The Old Taxiarchis".
The new church of Taxiarchis is located where the central circular tower of the castle used to be.
The Tower of Militas
The main road from the proskynima leads to the Northwest side of the castle, the so called "tower of Militas". It derives from the Italian word militare which means army. The tower can be seen more clearly from the square outside the castle and nowadays it has become a residence. The reason it was named after this word is because it was reinforced by a military force since it is located facing the sea from where all raids were expected.
The Tower
The Tower is one of the five towers the castle used to have on the corners of its pentagonal part. It is circular and consists of two floors which communicate through a spiral staircase. Only four of the towers are redeemed nowadays (unfortunately, the one located at the corner where the parking area is these days has been destroyed). One of the four existing ones is now a residence, a very unique one since it has circular rooms. The towers used to be in direct contact with each other through a tunnel parallel to the outer road.
The loopholes of the tower can be still noticed. From outside they look as narrow openings although from inside they look like tunnels. From the tower by taking the ring road one reaches the entrance of the village-castle.
The Gate of the Castle
The Gateway of the castle is named by the natives as "door of the captain", that means the door of the governor (it derives from the Italian word "capitano"). The monoliths of which it consists are remarkable as well as the iron door that remains in an excellent condition.
The Village Square
The villagers call it "Livadi". The square is a resort after an exhausting day. There is a particular reason that a daily stroll in the square is considered necessary. As it is obvious the house of the village and especially those which form the castle do not provide any open space or gardens since they are built in a way that unites them all.
Cave of Olympoi
Approximately 10 km From Mesta Village, the Cave of Olympoi is a phenomenal natural wonder that was discovered as recently as 1985. Guided tours began in 2002 and though the cave is relatively small, it is filled with beautyful structures formed by mineral deposits. With magnificent stalacties cascade from the ceiling- like folds of material while stalagmites emerge from the ground mimicking bubbling water frozen in mid-sprut. The tour goes to the depth of 30 m, though the cave extents to more than 50 m.
There is a small cafeand gift shop above ground, open during the high season.
The School
The idea of erecting a school building matured into the thought of the villagers for several years. The need for the erection of a new and modern School was born after the creation of the New Taxiarch. They used as a school, a small temple, the Temple of Sotiros, which were in the square of the village.
