This tower is everything what’s left from Livonian Knights Order castle built most likely in 14th century. It is located in the centre of town. Now in the tower is a town museum. It is very nice small museum, but I am not sure if the ticket seller/guide speaks English (or Russian). If not there won’t be much you will understand there. The best thing there was the small installation of central town square in different times: during Russian Empire in the begining of 20th century, during time of Latvian independence between both World Wars and during first years of Soviet Occupation in the middle of 20th century.
You can get to Tukums from Riga also by suburban train: http://www.1188.lv/satiksme?sub=vilcieni&PHPSESSID=4ce0592620033989a732d0620bcc79c6&lang=en. It is a little bit cheaper then bus, but take the same time to reach Tukums. These trains are going through Jurmala, so you can combine your visit to these two towns from Riga. There are two train stations in Tukums: Tukums-1 and Tukums-2. You should go off the the train at first of them (from Riga): Tukums-1, because this station is the one in centre. The other one is few km outside the town centre (on the opposite side to Slokenbeka).
There are frequent (each hour or sometimes often) buses from Riga. It takes 1-1.5 hours to get there depending on which bus you are taking. For prices and timetable for this and other bus routes check this link: http://www.1188.lv/satiksme?sub=autobusi&lang=en.

This little „castle” was built in late 15th or early 16th century by vassal (liege) of Livonian Knights Order. Such fortified medieval house is some kinda unique in Latvia. Now in this building is a museum for Latvian road building history. It is located few km outside Tukums in direction to Smarde in village called Milzkalne, so the best option is if you are coming by car. But you can take a taxi there from Tukums. I don’t know about the price – it could be 5 Ls or 10 Ls, but I am really not sure about this. If it’s summer and you have a time then maybe you can even walk (or/and hitching – at least back to Tukums) there – it will take few hours there and back, if you decide to walk, I suppose.
